Question

Find a quadratic polynomial, the sum and product of whose zeroes are-7 and-18 respectively

Answer 1

here sum of polynomial=-b/a=-7/1
and product=c/a=-18/1 it means that b=7
c=-18and a=1
so polynomial is x^2+7x-18
u should mark this as brainiest if u like this

Answer 2

p(x) = x²+7x-18
use relationship between zeroes and coefficients
