Use the method of your choice to factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$3 x^{2}-5 x+1$$

In Exercises \(27-44,\) factor completely, or state that the polynomial is prime. $$3 x^{3}+15 x$$

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. $$7 y^{4}+14 y^{3}+7 y^{2}$$

Use the method of your choice to factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$10 y^{2}+43 y-9$$

Use factoring to solve quadratic equation. Check by substitution or by using a graphing utility and identifying \(x\)-intercepts. \(5 x^{2}=18-x\)

In Exercises \(27-44,\) factor completely, or state that the polynomial is prime. $$18-2 y^{2}$$

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. $$9 x^{4}+18 x^{3}+6 x^{2}$$

Factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$x^{2}+7 x y+6 y^{2}$$

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. $$2 y^{4}+28 y^{3}+98 y^{2}$$

Factor each trinomial, or state that the trinomial is prime. Check each factorization using FOIL multiplication. $$x^{2}+6 x y+8 y^{2}$$
