Question

Find the quadratic equation polynomial whose zeroes are -2 and -5 verify the relationship between zeroes and coefficient of the polynomial​

Answer 1

Answer:

x²+7x+10=0

Step-by-step explanation:

Let roots be r1 and r2

r1=-2, r2=-5

let the quadratic equation be ax²+bx+c=0

now, r1+r2= -b/a and r1*r2=c/a

Equation x²-b/a x+ c/a

= x²-(-7)x+10. =x²+7x+10=0
