Question

Simplify the following​

Answer 1

Answer:

v. p - (p -q) - ( q - p) - q

= p - p + q - q + p - q

= p - q

vi. 3a - 2b - ab -( a- b + ab) + 3ab +b - a

= 3a - 2b - ab - a +b - ab + 3ab +b - a

= 3a - 2a -2b + 2b + 3ab - 2ab

= a + ab

$vii. (3 {y}^{2} + 5 y- 4) - (8y - {y}^{2} - 4) \\ = 3 {y}^{2} + 5y - 4 - 8y + {y}^{2} + 4 \\ = 4 {y}^{2} - 3y$
