Trig: Solve Quadratic Equations by Factoring help with 2b and 2c

Step-by-step explanation:

To factor ax² + bx + c, use the AC method.

(b) 3x² + 11x − 4 = 0

(3x − 1) (x + 4) = 0

3x − 1 = 0, or x + 4 = 0

x = 1/3, or x = -4

(c) 12x² + 8x = 0

Here, you can simply factor the greatest common factor, 4x.

4x (3x + 2) = 0

4x = 0, or 3x + 2 = 0

x = 0, or x = -2/3

where are the images of the functions i can only see the question you typed.
