Chapter Review If P(x)=4x3-5x-2, use synthetic substitution to find: P(2) P(-0.5) P(i) If 2 is a zero of P(x)=3x2+kx-8, find the value of k. When a polynomial P(x) is shared out by x+3, the quotient is x2-x+5 and the remainder is 2. Find P(x). both roots of the comparability x4-3x3-14x2+12x+40=0 are x=2 and x=5. Find the remaining root. Sketch the represent of y=x(x+1)(x-2)2. Give an equation of the cubic graph shown at the right. A rectangular enclosure is to be made utilise a barn as one side and 80m of inclose to form the other three sides. What is the maximum area of such an enclosure?
