Question

Plzzzzzzz help me to factorize fhis.....
4y^2- 4yx + x^2- 9z^2

Answer 1

Answer:

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

Explanation:

4y²-4yx+x²-9z²

= [(2y)²-2*2y*x+x²]-(3z)²

=(2y-x)²-(3z)²

______________________

We know the algebraic identity:

a²-b² = (a+b)(a-b)

_____________________

=[(2y-x)+3z][(2y-x)-3z]

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