Question

Ejemplos de factor común por agrupacion

Answer 1

17ax – 17mx + 3ay - 3my + 7az – 7mz = a(17x +3y +7z) - m(17x + 3y +7z)
= (17x +3y +7z)(a – m)m(x + 2) – x – 2 + 3(x + 2) = (x + 2)(m + 3) -1(x + 2) = (x + 2)[(m + 3) – 1]
= (x + 2)(m + 3 – 1)Otra forma de hacerlo:m(x + 2) – x – 2 + 3(x + 2) = m(x + 2) -1(x + 2) + 3(x + 2) = (x + 2)(m + 3 -1)
