Question

Factories
xy(1+z²)+z(x²+y²)​

Answer 1

S O L U T I O N:

Given,

= xy(1 + z²) + z(x² + y²)

= xy + xyz² + zx² + zy²

On grouping, we get,

= xy + zx² + xyz² + zy²

= x(y + xz) + yz(xz + y)

= x(y + xz) + yz(y + xz)

Taking y + xz as common, we get,

= (y + xz)(x + yz)

★ So, the factorised form is - (y + xz)(x + yz)

A N S W E R:

• (x + yz)(y + xz)
