Question

if the sum of the zeros is - 1 and the product is 7 wrte the quadratic polynomial​

Answer 1

Let p and q be roots of equation

given p+q=-1. and pq=7

general quadratic equation is x^2-( p+q)x+pq=0

hence quadratic equation is x^2-(-1)x+(7)=0

x^2+x+7=0

Answer 2

Given:

sum of zeroes= -1; product =7

Quadratic equation formula is

K[x^2-x(sum of zeroes)+product of zeroes]

Substituting all these values , we get

• K[x^2-x(-1)+7]
• K[x^2+x+7]
• If K = 1, then the Quadratic equation is
• x^2+x+7
