11-64.

Solve each of the following equations or systems. Homework Help ✎

*x*^{2}− 1 = 15*y*= 3*x*− 2

*y*= 4*x*+ 3*x*^{2}− 2*x*− 8 = 02

*x*^{2}= −*x*+ 7

Add 1 to both sides.

*x*^{2} = 16

Solve for *x*.

*x* = ± 4

Set the equations equal to each other.

3*x* − 2 = 4*x* + 3

Solve for *x*.

Factor the equation using a generic rectangle.

(*x* − 4)(*x* + 2) = 0

Solve for *x*.

Set the equation equal to zero.

Use the quadratic formula.
