Answer:

$x> \frac{8}{51}$

Step-by-step explanation:

$7x - \frac{5}{8} x + 3>4$

Bring constants to one side, simplify:

$\frac{51}{8} x>4 - 3 \\ \frac{51}{8} x>1 \\ x>1 \div \frac{51}{8} \\ x>1 \times \frac{8}{51} \\ x> \frac{8}{51}$

*Note that the inequality sign only changes when you divide the whole inequality by a negative number.

The get (x-1)(x-√2)(x+√2)(x-√3)(x+√3).

Expanding, you get x^5-x^4-5x^3+5x^2+6x-6.
