Question

3(−ab3+2ab2−3ab+2)−2(5ab3−6ab2+10ab)

Answer 1

SOLUTION

TO EVALUATE

$\sf{3( - a {b}^{3} + 2a {b}^{2} - 3ab + 2) - 2( 5a {b}^{3} - 6a {b}^{2} + 10ab)}$

EVALUATION

$\sf{3( - a {b}^{3} + 2a {b}^{2} - 3ab + 2) - 2( 5a {b}^{3} - 6a {b}^{2} + 10ab)}$

$\sf{ = ( -3 a {b}^{3} + 6a {b}^{2} - 9ab + 6) - ( 10a {b}^{3} - 12a {b}^{2} + 20ab)}$

$\sf{ = -3 a {b}^{3} + 6a {b}^{2} - 9ab + 6 - 10a {b}^{3} + 12a {b}^{2} - 20ab}$

$\sf{ = -13 a {b}^{3} + 18a {b}^{2} - 29ab + 6 }$
