And the reciprocal of something more complicated like "x/y" is "y/x". (Subtraction) 1+2, Matrix Calculator. Thank you. Thank you. Square Root. Reciprocal of X/Y = Y/X As can be see from the equation above, the reciprocal is another word for opposite. ^ 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. Algebra Calculator is a calculator that gives step-by-step help on algebra problems. Trigonometry Calculator. Please use at your own risk, and please alert us if something isn't working. 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. 4x+2=2(x+6) (Solve Example), 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. Try MathPapa 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. Thank you. 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.
