Solve Quadratic Equation Using the Grouping (AC) Method.

2022年8月4日 · The expressions that represent quadratic expressions are B: 5 x 2 and E: 8 x 2 − 7 x + 1. If we are to select one unique answer, option E is a complete quadratic polynomial. Quadratics can be recognized by the highest power of 2 in their terms.

Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = (a + b) (a - b) where a = 3x a = 3 x and b = 2y b = 2 y. Multiply 2 2 by −1 - 1.
