Factor the numerator and the denominator. Then simplify by dividing out the common factor in the numerator and the denominator. \(\frac{x^{2}+6 x+5}{x^{2}-25}\)
Use factoring to solve quadratic equation. Check by substitution or by using a graphing utility and identifying \(x\)-intercepts. \(x(x-3)=18\)
Exercises \(150-152\) will help you prepare for the material covered in the next section. Evaluate \((3 x-1)(x+2)\) for \(x=\frac{1}{3}\)
Use factoring to solve quadratic equation. Check by substitution or by using a graphing utility and identifying \(x\)-intercepts. \(x(3 x+8)=-5\)
Use the \(x\)-intercepts for the graph in \(a[-10,10,1]\) by \([-13,10,1]\) viewing rectangle to solve the quadratic equation. Check by substitution. Use the graph of \(y=x^{2}+3 x-4\) to solve \(x^{2}+3 x-4=0\).
