Answer:
(2a+b+1)(2a+b-4)
Step-by-step explanation:
Given that
(2a+b)^2 - 6a -3b -4
(2a+b)^2 - 3 (2a+b) - 4 = 0
Assume x = 2a + b
x^2 - 3x - 4 = 0
x^2 - 4x + x - 4 = 0
x(x-4) + 1(x-4) = 0
(x + 1) (x-4) = 0
Substitute x = 2a + b in the above equation , we will get
(2a+b+1)(2a+b-4) = 0
Hope it helps you.
