Solve Polynomial Inequality...1

[nycmathguy]

Section 2.7
Question 16

Solve for x.

sqrt{x^2} = sqrt{25}

x = -5 & x = 5

See attachment.

As you can see, the inequality is satisfied in the closed interval [-5, 5] including x = -5 & x = 5.

You say?

I totally forgot to graph the solution. More Section 2.7 questions tomorrow. Check out three extra post in the Geometry and Trigonometry forum.
