Answer:

Equation : (3x + 1)^2 - 4(x-1)^2

Answer : (11x+1) (7x+5)

Step-by-step explanation:

(3x + 1)^2 - 4(x-1)^2

[3(3x+1)]^2 - [2(x-1)]^2

(9x + 3)^2 - (2x-2)^2

We know a^2 - b^2 = (a+b) (a-b)

(9x + 3 +2x - 2) [9x + 3 -(2x-2)]

(9x + 3 +2x - 2) (9x + 3 - 2x + 2)

(9x + 2x +3 -2) (9x - 2x +3 + 2)

Required Answer:- (11x + 1) (7x + 5)
