Question

expand using suitable identity (x-4y+3z)2

Answer 1

heya mate here is your answer

using identity (a+b+c)² = a² + b²+c² +2(ab+bc+ca)

(x)² + (-4y)² +(3z)²+2(-4yx+12yz-4xz)

${x}^{2} + 16 {y}^{2} + 9 {z}^{2} - 8xy - 24yz \\ + 6xz$

hope it helps you

Answer 2

UR ANSWER IS:

using identity (a+b+c)² = a² + b²+c² +2(ab+bc+ca)

(x)² + (-4y)² +(3z)²+2(-4yx+12yz-4xz)

2+16y2+9z2−8xy−24yz+6xz
