how do you solve sqroot(3x - 1) > x + 7?

Welcome and Thanks for using Just Answer.

√(3x - 1) > x + 7

Squre both sides

3x - 1 > (x + 7)^2

3x - 1 > x^2 + 14x + 49

0 > x^2 + 11x + 50

x^2 + 11x + 50 < 0

The left hand side is a quadratic with a = 1, b = 11, c = 50

Its discriminant is b^2 - 4ac = 11^2 - 4 * 1 * 50 = -79

Since the discriminant is < 0, the quadratic has no real solutions

This means the inequality x^2 + 11x + 50 < 0 has no solution

Answer: √(3x + 1) > x + 7 has no solution
