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

Only if the value of c is 9 because:- 4x2+12x+9 = (2x+3)(2x+3)

If you can't factor it easily, use the quadratic formula.

4x2 - 13 x + 3 = 0 (4x - 1)(x - 3) = 0 x = 3, 1/4

The equation y = 4x^2 + 5 is a parabola

4x2 = -12x, divide both sides by 4x: x = -3

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

You need to rivse your question. It appears that there is not an equation here. 4*2+12x+9? You can't really solve this it is more of a statement. You can however simplify it to 12x+17- Whoever wrote this obviously can't read. It's supposed to be 4x^2+12x+9 (2x+3)(2x+3)

4x2+12x = 4x(x+3) when factored

12x * 4x2 = 48x3

Only if the value of c is 9 because:- 4x2+12x+9 = (2x+3)(2x+3)

There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.

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

4(x + 2)(x + 1)

(2x+5)(2x+1)

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

(2x + 3)(2x + 3)
