Solve 4a^2-9b^2-2a-3b

Evaluate

4 a^{2} - 9 b^{2} - 2 a - 3 b

Calculate

4 a^{2} - 6 ab - 2 a + 6 ba - 9 b^{2} - 3 b

Rewrite the expression

2 a \times 2 a - 2 a \times 3 b - 2 a + 3 b \times 2 a - 3 b \times 3 b - 3 b

Factor out 2 a from the expression

2 a (2 a - 3 b - 1) + 3 b \times 2 a - 3 b \times 3 b - 3 b

Factor out 3 b from the expression

2 a (2 a - 3 b - 1) + 3 b (2 a - 3 b - 1)

Solution

(2 a + 3 b) (2 a - 3 b - 1)

Factor the expression
