Question

factorize 7(x-2y)^2 - 25 (x- 2y) + 12​

Answer 1

Step-by-step explanation:

Given Equation is 7(x - 2y)² - 25(x - 2y) + 12

= 7(x - 2y)² - 21(x - 2y) - 4(x - 2y) + 12

= 7(x - 2y)[(x - 2y) - 3] - 4[(x - 2y) - 3]

= 7(x - 2y)[x - 2y - 3] - 4[x - 2y - 3]

= [7(x - 2y) - 4][x- 2y - 3]

= (7x - 14y - 4)(x - 2y - 3)
