(Multiplication) Reciprocal of a number; To find the reciprocal of a number, divide 1 by the number. The numbers a, b, and c are the coefficients of the equation and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term. Try MathPapa Algebra Calculator is a calculator that gives step-by-step help on algebra problems. Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √(x), where the symbol √() is called the radical sign or radix. (Exponent: "raised to the power") If you would like to create your own math expressions, here are some symbols that the calculator understands: + In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. Comments and suggestions are very much appreciated! 2x^2+2y @ x=5, y=3 (Evaluate Example) - Thank you. Math Practice, Stay up to date with the latest news and offers from MathPapa. The following formula is used to calculate the reciprocal of a fraction. Need more practice problems? So, Now, switching the numerator and denominator of the last fraction, we find that the reciprocal of 15 8 is 8 13. 1/3 + 1/4. 2^3 * 2^2 (x+1)(x+2) (Simplify Example), Type your algebra problem into the text box.

Get the MathPapa mobile app! Disclaimer: This calculator is not perfect. Reciprocal of a Variable Likewise, the reciprocal of a variable "x" is "1/x". (Addition) Example: the reciprocal of 3/4 is 4/3. Examples: Solvers Solvers. 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. Square Root. In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. Trigonometry Calculator. ^ Example: the reciprocal of 7 is 1/7 1/3+1/4, Reciprocal of X/Y = Y/X As can be see from the equation above, the reciprocal is another word for opposite. Algebra Calculator. Matrix Calculator. sqrt (Square Root) (Example: sqrt(9)) See More Examples ». (Division) 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. Disclaimer: Step 3: Write that result (13) above the denominator. To find the reciprocal of a fraction, switch the numerator and the denominator (the top and bottom of the fraction, respectively). y=x^2+1 (Graph Example), If a = 0, then the equation is linear, not quadratic, as there is no ax² term. The decimal number 0.5 can be written as 0.5/1. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. Please leave a suggestion. * And the reciprocal of something more complicated like "x/y" is "y/x". For example, to find reciprocal of 0.5, find the equivalent fraction for 0.5.
