Question

Factorise
$factorise 4x + 9y + 16z + 12xy - 24yz - 16xz \: please solve this question tommorrow i having a maths exam$

Answer 1

Answer:

4x+ 9y + 16z + 12xy - 24yz - 16xz

We know that,

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

Similarly,

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

Good luck on the exam, feel free to ask any more questions
