Hey!!!!
__________
Let p(x) = ax³ + 3x² - 3
and f(x) = 2x³ - 5x + a
=> p(x) is divided by x + 1
=> For remainder p(-1)
=> p(-1) = a(-1)³ + 3(-1)² - 3
=> - a + 3 - 3
=> - a -------(R1)
Similarly
=> f(x) is divided by x + 2
=> p(-2) = 2(-2)³ - 5(-2) + a
=> 2(-8) + 10 + a
=> a - 6 ------- (R2)
Condition = R2 - 2R1 = 0
Let's put values
=> a - 6 + 2a = 0
=> 3a = 6
=> a = 2
__________
Hope this helps ✌️
