Question

(4y²-12xy+9x²)-4z² factorize

Answer 1

(
$(4y {}^{2} - 12xy + 9x {}^{2} ) - 4z {}^{2} \\ \\ ((2y) {}^{2} - 2(2y)(3x) +( 3x) {}^{2} ) -(2z) {}^{2} \\ \\ (2y - 3x) {}^{2} - (2z) {}^{2} \\ \\ (2y - 3x + 2z)(2y - 3x - 2z)$

Answer 2

Answer:

4y2−12xy+9x2)−4z2((2y)2−2(2y)(3x)+(3x)2)−(2z)2(2y−3x)2−(2z)2(2y−3x+2z)(2y−3x−2z)
