2)Question
10m²-9m+7m-3m²-5-8
STEP BY STEP LIKE SOLUTION​

Answer 1

Answer:

$\huge \sf{your \: answer - }$

$3{a}^{2}-{b}^{2}+7 {a}^{2}-ab+4 {b}^{2}+5ab$

$3 {a}^{2} + 7 {a}^{2} - {b}^{2} + 4 {b}^{2} - ab + 5ab$

$10 {a}^{2} + 5 {b}^{2} + 6ab$

$\bold \red{your \: answer \: is \: proved}$

question number 2:-

$10 {m}^{2} - 9m + 7 - 3 {m}^{2} - 5 - 8$

$10 {m}^{2} - 3 {m}^{2} - 9m + 7 - 5 - 8$

$7{m}^{2} - 9m - 6$

$\bold \green{your \: this \: answer \: is \: also \: proved}$
