Question

Resolve into factos: (xy+z²) + (y-xz²)

Answer 1

Answer:-

$\\ \sf \longmapsto (xy+z)^2+(y-xz^2)$

$\boxed{\sf (a+b)(c+d)=a(c+d)+b(c+d)}$

• Using distributive law

$\\ \sf \longmapsto xy(y-xz^2)+z^2(y-xz^2)$

$\\ \sf \longmapsto xy^2-x^2yz^2+yz^2-xz^4$

• take y common

$\\ \sf \longmapsto y(xy-x^2z^2+z^2-xz^2)$
