- To solve a polynomial inequality, we factor the polynomial into irreducible factors and find all the real _______of the polynomial. Then we find the intervals determined by the real____ and use test points in each interval to find the sign of the polynomial on that interval. Let P(x)=x(x+2)(x1) Fill in the diagram below to find the intervals on which P(x)0. From the diagram above we see that P(x)0 on the intervals _____ and _____ .arrow_forwardComplete Factorization A polynomial P is given. (a) Find all zero of P, real and complex. (b) Factor P completely. P(x)=x4x22arrow_forwardGraphing Polynomials Factor the polynomial and use the factored form to find the zeros. Then sketch the graph. P(x)=x3+x2x1arrow_forward
