WebTo subtract algebraic fractions, first express them in terms of their Lowest Common Denominator and then subtract their numerators to obtain the numerator that is divided by the LCD to arrive at the answer. Example 15. Solution: Useful Device: Sometimes we use: to simplify algebraic expressions. WebIn algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.) The numbers a, b, and c are the coefficients of the equation ...
