plz solve this sums very quick..​

Answer 1

Heya mate!!

These questions will be solved by identities.

${a}^{2} + 2ab + {b}^{2} \\ {a}^{2} - 2ab + {b}^{2}$

$25 {m}^{2} + 40m + 16 \\ \sqrt{25 {m}^{2} } + 2 \times 5 \times 4 + \sqrt{16} \\ 5m + 4$

$144 {b}^{2} - 120bc + 25 {c}^{2} \\ \sqrt{144 {b}^{2} } - 2 \times 12 \times 5 + \sqrt{25 {c}^{2} } \\ 12b - 5c$

Hope it helps u dear✌️✌️
