How do you solve #4x^2+28x-32=0# by factoring?
Refer to explanation
We can write it as follows
Ans: 1 and -8
Because (a + b + c = 0), use Shortcut. The 2 real roost are: x = 1 and
REMINDER of the SHORTCUT.
1. When (a + b + c = 0), the 2 real roots are: x = 1 and
2. When (a - b + c = 0), the 2 real roots are x = - 1 and
