Question

Write a quadratic polynomial, sum of whose zeroes is -7 and product is -18​

Answer 1

Step-by-step explanation:

Let a & b be the zeros of polynomial f(x)

Then, (a+b) = -7 and ab = -18

Since, f(x) = x^2-(a+b) x+ab

= x^2-(-7) x +(-18)

=x^2+7x-18

Hence, the required polynomial is f(x) = x^2+7x-18
