Question

Factorise using suitable identity :- 36m² - 36m +9​

Answer 1

36m²-36m+9

(6m)²-2×6m×3+3²

it's in the form a²-2ab+b² =(a - b)²

a=6m , b=3

(6m-3)²

Answer 2

Answer:

(18m-9)(2m-1)

Step-by-step explanation:

${36m}^{2} - 36m + 9 \\ = {36m}^{2} - 18m - 18m + 9 \\ = 18m(2m - 1) - 9(2m - 1 \\ = (18m - 9)(2m - 1) \: ans$
