            Ignore the post by @josgarithmetic since it is INCORRECT.

            The correct solution is below.

4x^2- 100 < 20 Add 100 to both sides 4x^2 < 20 + 1200 4x^2 < 120 Divide by 4 both sides x^2 < 30 Take the square root of both sides < x < . ANSWER

Solved.

            Ignore the post by @josgarithmetic after his correction, too, since it is STILL INCORRECT.
