It may be easier to start from

.. a(x +3)(x -1) = 0
.. a(x^2 +2x -3) = 0

The quadratic
.. ax^2 +bx +c = 0 will have solutions -3 and 1 for ...

.. a ≠ 0
.. b = 2a
.. c = -3a

What are the solutionso of 8x^2 = 6 + 22x
liraira [26]
You can get all the terms on one side, and then solve for x by any means:
0 = -8x^2+22x+6

Factor out a -2:
0 = -2(4x^2-11x-3)

Factor this equation:
0 = 4x^2-11x-3

I will use the AC method. To use it, first multiply a and c (in ax^2 + bx +c):
4*-3 = -12

Now, look for two numbers that multiply to -12 and add to -11. Obviously these numbers are -12 and 1. (-12*1 = -12 and -12+1  = -11). Now, because of rules, you set it up in a Punnett square:

4x^2        -12x
x              -3

Now, we find common factors of the terms in rows:
     _x_______-3__
4x| 4x^2        -12x
1   | x              -3

So, you can use this to write an equivalent expression to the quadratic given:
(x-3)(4x+1)

Now, we known the factors are (solve for x): 3 and -1/4.
