Question

foctorise 36x^2- 36x + 9​

Answer 1

Answer:

36x^2- 36x + 9

36x² -36x +9 = 0

divide by 9 both sides

we get

4x² -4x +1 = 0

4x² -2x -2x +1 =0

2x(2x -1)-1(2x-1) =0

(2x-1)(2x-1) =0

this implies x=1/2, 1/2

Answer 2

Step-by-step explanation:

given

$36 {x}^{2} - 36x + 9 \\ \\ first \: take \: 9as \: common \\ \\ 9(4 {x}^{2} - 4x + 1) \\ \\ 9(4x {}^{2} - 2x - 2x + 1) \\ \\ make \: a \: pair \: n \: take \: common \\ \\ 9(2x(2x - 1) - 1(2x - 1) \\ \\ 9(2x - 1)(2x - 1)$
