Question
Solve by factoring.See Example 1.See the Strategy for Solving Quadratic Equations by Factoring box on page 522.$$x^{2}+6 x+8=0$$
Step 1
We are looking for two numbers that multiply to 8 (the constant term) and add to 6 (the coefficient of the x term). The numbers that satisfy these conditions are 2 and 4. So, we can write the quadratic equation as follows: $$x^{2}+6 x+8=(x+2)(x+4)=0$$ Show more…
