Answer» Find the zeros of each of the following quadratic polynomial and verify the relationship between the zeros and their coefficients:



(i) f(x) = x2 − 2x − 8

(ii) g(s) = 4s2 − 4s + 1

(iii) h(t) = t2 − 15

(iv) 6x2 − 3 − 7x

(v) px=x2+22x-6

(vi) qx=3x2+10x+73

(vii)fx=x2-3+1 x+3

(viii) g(x) = a(x2 + 1) − x(a2 + 1)

(ix) hs=2s2-1+22s+2

(x) fv=v2+43v-15

(xi) py=y2+352y-5

(xii) qy=7y2-113y-23
