Then, factor the polynomial 4x2-36. Use three or more sentences to describe how you identify whether or not a polynomial is a perfect square trinomial. Then, factor the polynomial x2-40x+400. Consider the factoring process that has been illustrated below. Use three or more sentences to describe the process used to factor this polynomial. 3y3+4y2-12y-16 =y2(3y+4)-4(3y+4) =(3y+4)(y2-4) =(3y+4)(y+2)(y-2) Use three or more sentences to describe the process you would follow to completely factor the polynomial 3x6+24.
