Given a general quadratic equation of the form ax²+bx+c=0 with x representing an unknown, a, b and c representing constants with a ≠ 0, the quadratic formula is: where the plus-minus symbol "±" indicates that the quadratic equation has two solutions. (Subtraction) Algebra Calculator. Thank you. It works offline! Type a math problem. For example, to find reciprocal of 0.5, find the equivalent fraction for 0.5. To find the reciprocal of a fraction, switch the numerator and the denominator (the top and bottom of the fraction, respectively). sqrt (Square Root) (Example: sqrt(9)) The decimal number 0.5 can be written as 0.5/1. - Algebra Calculator is a calculator that gives step-by-step help on algebra problems. y=x^2+1. ^ Disclaimer: This calculator is not perfect. Examples: Reciprocal of X/Y = Y/X As can be see from the equation above, the reciprocal is another word for opposite. Type your algebra problem into the text box. 1+2, And the reciprocal of something more complicated like "x/y" is "y/x". Step 2: Add the product from Step 1 (8) to the numerator (5). / For example, 4 and −4 are … This calculator is not perfect. An inverse of 1/2 is 2, so the reciprocal of decimal number 0.5 is 2. 1/3 + 1/4. In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. Please let us know if you have more feedback to help us improve: Don't see the feature you need? Please use at your own risk, and please alert us if something isn't working. Step 1: Multiply the whole number part (1) by the denominator (8). (Addition) Solvers Solvers. An inverse of fraction is a reciprocal of decimal number. Example: the reciprocal of 3/4 is 4/3. The procedure to use the reciprocal of a fraction calculator is as follows: Step 1: Enter the fraction in the input field Step 2: Now click the button “Solve” to get the multiplicative inverse Step 3: Finally, the reciprocal of the given fraction will be displayed in the output field  y=x^2+1 (Graph Example), If a = 0, then the equation is linear, not quadratic, as there is no ax² term. In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. 方程組（英語：system of equations）又稱聯立方程（simultaneous equations），是兩個或兩個以上含有多個未知數的方程聯立得到的集。未知數的值稱為方程組的根，求方程組根的過程稱為解方程組。一般在方程式的左邊加大括號標注。 解方程組的方法大致上有畫圖法、代入法、消元法（包括高斯消元法）、矩陣法（包括克萊姆法則）等。, Solving Square Root / Cube Root Equations Pre-Algebra / Algebra 1, Quadratics the Fundamental Theorem of Algebra, Solving quadratic equations by factoring (old), Method of Substitution Steps to Solve Simultaneous Equations. Thank you. Matrix Calculator. So, simply speaking, the reciprocal of a/b is b/a. Please use this feedback form to send your feedback. Try MathPapa If you would like to create your own math expressions, here are some symbols that the calculator understands: + (Division) algebra trigonometry statistics calculus matrices variables list. Square Root. See More Examples ». Thank you. Calculus Calculator. Reciprocal of a Variable Likewise, the reciprocal of a variable "x" is "1/x". Please leave a suggestion. Step 3: Write that result (13) above the denominator. Algebra -> Inverses-> Solver FIND reciprocal of a NUMBER Log On Algebra: Inverse operations for addition and multiplication, reciprocals Section. Lessons Lessons. For example, 4 and −4 are square roots of 16, because 4² = (−4)² = 16. How to Use the Calculator. For example, enter 3x+2=14 into the text box to get a step-by-step explanation of how to solve 3x+2=14. Solve. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. Need more practice problems? 2x^2+2y @ x=5, y=3 (Evaluate Example) (Exponent: "raised to the power") In other words turn it upside down. (Multiplication)
