Question

factorize 169m^2-130m^2n^2+25n^4

Answer 1

Step-by-step explanation:

$169 {m}^{4} - 130 {m}^{2} {n}^{2} + 25 {n}^{4} \\ {(13 {m}^{2}) }^{2} - 2 \times 13 {m}^{2} \times 5 {n}^{2} + {(5 {n}^{2} )}^{2} \\ {(13 {m}^{2} - 5 {n}^{2} ) }^{2} \\ (13 {m}^{2} - 5 {n}^{2} )(13 {m}^{2} - 5 {n}^{2} )$

using identity (a - b)² = a² - 2ab + b²

Hope you get your answer
