b = -2
maka, a²b + ab² = (5²) . (-2) + (5) . (-2)
= 25 . (-2) + (-10)
= -50 - 10
= -60
b = -2
a²b + ab²
= (5)² (-2) + 5(-2)²
= 25 × (-2) + 5 (4)
= -50 + 20
= 30
8)2p + 3q - 4 + p - 3q + 2
= 3p -2
9) a² - 2a - ( 2 - 3a² )
= a² - 2a - 2 + 3a²
= 4a²- 2a - 2
= 4a² - 4a + 2a - 2
= 4a (a-1) + 2(a-1)
= (4a + 2)(a - 1)
