7-113.

Solve each of the following equations. Be sure to check your solutions. Homework Help ✎

3 +

= 5 *x**x*^{2}+ 6*x*+ 9 = 2*x*^{2}+ 3*x*+ 58 –

= *x*+ 3

To remove the denominator, multiply both sides of (or each term in) the equation by (*x* + 1).

*x* = 4, −1

Subtract 8 from both sides and divide both sides by −1.

After setting the resulting equation equal to zero and solving the quatdratic equation, *x* = 4.

Square both sides and simplify.

9 − 2*x* = *x*^{2} − 10*x* + 25
