Solve x^2 - 12 < 4x
Solution (INTERVAL notation, no spaces)????
Answer by tommyt3rd(5050) (Show Source): You can put this solution on YOUR website!
x^2 - 12 < 4x
x^2-4x-12 < 0
(x-6)(x+2)<0
since this parabola has 2 real roots and opens upwards we know that between -2 and 6 it must be negative. So solution interval is (-2,6)
