Question

xy (z2 + 1) + z (x2 + y2) can be factorized as: (A) (xy + z) (yz + x) (B ) (zx + y) (xy + z) (C) (yz + x ) (zx + y) (D) (x2 + y2) (z + x)

Pratik Tibrewal · Accepted Answer

it is (C)xyz^2 + xy + zx^2 + zy^2= xyz^2 + zx^2 + xy + zy^2= xz(yz + x) +y(zy + x)= (yz + x)(xz + y)Thanks and RegardsPratik Tibrewal,askiitians faculty,BTech
