Answer:

-5 ≤ x ≤ 5

Explanation:

If x^2 = 25

x = -5 or 5

BUT inequality

IF x is POSITIVE 5

You can square root both sides

x ≤ 5

IF x is NEGATIVE 5

You can divide both sides by -5

BUT switch inequality sign

This is because basically dividing both sides by negative

x ≥ -5

FINAL INEQUALITY

-5 ≤ x ≤ 5
