Question

7) usando a técnica de agrupamento fatore os polinômios A) AB-AC+4B-4C=?? B) 6x+6y+hx+hy=?? C) a²-7a+2ax-14x=?? Me ajudem pfv

Answer 1

A) AB-AC+4B-4C=  a(b-c) + 4(b-c) ==> (a+4)(b-c)

B) 6x+6y+hx+hy=?? 6(x+y) + h(x+y) ==> (6+h)(x+y)

C) a²-7a+2ax-14x ==> a(a-7) + 2x(a - 7) ==> (a+2)(a-7)

Answer 2

a) ab-ac+4b-4c= a(b-c) + 4(b-c) = (b-c)(a+4)
b) 6x+6y+4x +hy= 6(x+y) + h(x+y)  = (x+y) (6h)
c) a² - 7a + 2ax - 14x = a(a-7) + 2x(a-7) =  (a-7) (a+2x)
