Question

Find the missing factor.w^2(x + 8) + z(x + 8) = (?)(x + 8)

Answer 1

We have

$w^2\mleft(x+8\mright)+z\mleft(x+8\mright)=(?)\mleft(x+8\mright)$

as we can see the common factor is (x+8), therefore the missing factor is

$\mleft(w^2+z\mright)$

so the expression will be

$w^2\mleft(x+8\mright)+z\mleft(x+8\mright)=(w^2+z)\mleft(x+8\mright)$
