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 · 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 Regards Pratik Tibrewal, askiitians faculty, BTech
