Question

Factorise:

4 x2 + 9y2 + 16z2 + 12xy – 24yz – 16xz​

Answer 1

Answer:

1. x2 - 196 = 0

II. y- √196 = 0 it is already factories in above question

Answer 2

Answer:

=4x²+9y²+16z²+12xy-24yz-16xz

=(2x) ²+(3y) ²+(-4z) ²+2×2x×3y+2×3y×(-4z) +2×(-4z)

×2x

=(2x+3y-4z) ²

Step-by-step explanation:

HERE THE FORMULA OF (a+b+c) ²=a²+b²+c²+2ab+2bc+2ca HAS BEEN USED.
