Question

find a quadratic polynomial whose zeroes are 1 and -3. verify the relation between the coefficients and zeroes of the polynomail

Answer 1

factors

=(x-1)(x+3)

=xsquare-x+3x-3

=xsquare+2x-3

now,

sum of zeroes =-b/a

1-3=-2/1

-2=-2

product of zeroes =c/a

1×-3=-3/1

-3=-3

Hence,verified
