Answer 2

Answer:

9a2 + 4x2 – 2yz – z2 – y2 -12ax

=(3a-2x)²- (z²+2yz+y²)

=(3a-2x)²- (z²+2yz+y²)=(За - 2х)²- ( z + y)²

=(3a-2x)²- (z²+2yz+y²)=(За - 2х)²- ( z + y)²={3a - 2x - (z+y)} × {3a - 2x + (z+ y)}

=(3a-2x)²- (z²+2yz+y²)=(За - 2х)²- ( z + y)²={3a - 2x - (z+y)} × {3a - 2x + (z+ y)}=(3a - 2x - z - y) (3a - 2x + z + y)
