State whether the trinomial has a factor of \(x+3\) a. \(3 x^{2}-3 x-36\) b. \(x^{2} y-x y-12 y\)
Factor by grouping. $$8-7 x-x^{2}$$
Factor by grouping. $$10 z^{2}-29 z+10$$
Information is given about the signs of \(b\) and \(c\) in the trinomial \(a x^{2}+b x+c,\) where \(a>0 .\) If you want to factor \(a x^{2}+b x+c\) by grouping, you look for factors of \(a c\) whose sum is \(b\). In each case, state whether the factors of \(a c\) should be two positive numbers, two negative numbers, or one positive and one negative number. \(b>0\) and \(c>0\)
Factor by grouping. $$35 a^{4}+9 a^{3}-2 a^{2}$$
