Factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$x^{2}-2 x-8$$

Use factoring to solve quadratic equation. Check by substitution or by using a graphing utility and identifying \(x\)-intercepts. \(x^{2}-5 x=0\)

Factor each polynomial using the greatest common factor. If there is no common factor other than 1 and the polynomial cannot be factored, so state. $$30 x-12$$

Now let's move on to factorizations that may require two or more techniques. In Exercises \(17-80,\) factor completely, or state that the polynomial is prime. Check factorizations using multiplication or a graphing utility. $$6 x^{3}+24 x$$

In Exercises \(1-26,\) factor each difference of two squares. $$9 x^{2}-25 y^{2}$$

Factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$x^{2}-5 x-6$$

Use factoring to solve quadratic equation. Check by substitution or by using a graphing utility and identifying \(x\)-intercepts. \(x^{2}+3 x=0\)

Factor each polynomial using the greatest common factor. If there is no common factor other than 1 and the polynomial cannot be factored, so state. $$32 x-24$$

Use the method of your choice to factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$6 w^{2}-17 w+12$$

Use factoring to solve quadratic equation. Check by substitution or by using a graphing utility and identifying \(x\)-intercepts. \(x^{2}=4 x\)
