find the polynomial whose zeroes are -5 and 4

1.	find the polynomial whose zeroes are -5 and 4
Answer» Sum of zeros = –5 + 4 = – 1,Product of zeros = – 5 × 4 = – 20Required polynomial = x2 + x – 20 Polynomial will be (x square + x - 20) Firstle we find sum and product of zeroes and then we put this in xsquare-(alpha+beeta)x+alpha beeta The equation is (x square +x -20)
