MAT 121 Final 7. DETAILS 0/2 Submissions Used 40 29 20 Suppose the graph of p(x)=x-10x2+42x-72 is shown above. (a) Determine the unique real root of p from the graph. () Determine a linear factor of p(x) with real coefficients and with leading coefficient 1. (c) Use the linear factor of p(x) above, and long division, to determine an irreducible quadratic factor of p(x) with leading coefficient 1. (d) Determine the remaining two non-real zeros of p. (e) Factor P(x) completely into a product of linear factors using complex coefficients. P(x)=
