Question

Factorise (2x-3)^2 -8x+12.
​

Answer 1

Step-by-step explanation:

$(2x - 3) {}^{2} - 8x + 12 \\ = (2x - 3)(2x - 3) - 4(2x - 3) \\ = (2x - 3)(2x - 3 - 4) \\ = (2x - 3)(2x - 7)$

Answer 2

Answer:

(2x-3)(2x-7)

Step-by-step explanation:

(2x-3)² - 8x + 12 =

Now factorising 4x² - 20x + 21

u get (2x-3)(2x-7)
