Find a quadratic polynomial whose zeroes are-4 & -5

Answer 1

Hey there,

Sum of the roots = -4-5 = -9

product of the roots = -4(-5) = 20

Form of an quadratic equation = x2-(sum of roots)x+(product of roots)

=> x2-(-9)x+20

=> x2+9x+20

Therefore the quadratic polynomial is x2+9x+20

hope this helps
