Determine the factors of x2 − 12x − 20
WebOct 6, 2024 · Factoring Using the AC Method. An alternate technique for factoring trinomials, called the AC method, makes use of the grouping method for factoring four-term polynomials. WebAlgebra. Factor x^2-25y^2. x2 − 25y2 x 2 - 25 y 2. Rewrite 25y2 25 y 2 as (5y)2 ( 5 y) 2. x2 − (5y)2 x 2 - ( 5 y) 2. 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 = x a = x and b = 5y b = 5 y. (x+5y)(x−(5y)) ( x + 5 y) ( x - ( 5 y))
