4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).

(2x - 5)(2x - 5) or (2x - 5) squared

2(2x^2 + 2x - 5)

(2x + 5)(4x2 - 10x + 25)

3x+5 = 2x+13 3x-2x = 13-5 x = 8

4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).

4x2 + 12x + 5 = (2x + 1)(2x + 5).

4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
