Question

factorize 25 x^2 + 4y^ 2 + 9 z^2+ 20xy _ 12yz _ 30xz​

Answer 1

Step-by-step explanation:

25x^2 + 4y^2 + 9z^2 + 20xy - 12yz - 30xz

Can also be written as

(5x)^2 + (2y)^2 + (3z)^2 + 2(5x)(2y) + 2(2y)(-3z) + 2(5x)(-3z)

So by using identity

(5x + 2y + 3z)^2

(5x + 2y +3z)(5x + 2y +3z)

Is the Answer..
