Question

(7c³d²+2bc²d + ab) - (-4c³d² + ab - 7bc²d)

Answer 1

$( 7{c}^{3} {d}^{2} + 2b {c}^{2} d + ab) - ( - 4 {c}^{3} {d}^{2} + ab - 7b {c}^{2} d) \\ 7{c}^{3} {d}^{2} + 2b {c}^{2} d + ab+ 4 {c}^{3} {d}^{2} - ab + 7b {c}^{2} d) \\7{c}^{3} {d}^{2} + 4 {c}^{3} {d}^{2} + 2b {c}^{2}d + 7b {c}^{2} d + ab - ab \\ 11 {c}^{3} {d}^{2} + 9b {c}^{2} d$
