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. $$5 x^{2}-15 x-50$$

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. $$2 x^{4}-162$$

Factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$y^{2}-16 y+48$$

In Exercises \(1-26,\) factor each difference of two squares. $$x^{4}-16$$

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

Use the method of your choice to factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$5 x^{2}+33 x-14$$

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. $$20 y^{2}+15$$
