Question

how can I factorize. explain it in each step..

Answer 1

4m2-12m+9
4m2+6m+6m+9
2m (2m+3)+3 (2m+3)
(2m+3)(2m+3)


hope this will help u understand factorization

Answer 2

Ans.
1.
$4 {m}^{2} - 12m + 9 = 0 \\ or \: \: ( {2m})^{2} - 2.2m.3 + ({ 3})^{2} = 0 \\ or \: ( {2m - 3)}^{2} = 0 \\ or \: \: (2m - 3)(2m - 3) = 0$

2.
$4 {m}^{2} - 12m + 9 = 0 \\ or \: \: 4 {m}^{2} - 6m - 6m + 9 = 0 \\ or \: \: 2m(2m - 3) - 3(2m - 3) = 0 \\ or \: \: (2m - 3)(2m - 3) = 0$

I HOPE THAT THIS HELPS YOU.
