Question

If zeros of quadratic polynomial are -2 and 4 what is a quadratic polynomial?​

Answer 1

Answer:

Step-by-step explanation:

x2-(a + b) x +ab=0    (general format of polynomial)

let a=-2 and b=4

x2 -(-2+4)x+(-2)(4)=0

x2-(2)x+(-8)=0

x2-2x-8=0 is the polynomial.

CLARIFICATION:

x2-4x+2x-8=0

x(x-4) 2(x-4)=0

(x+2)(x-4)=0

x=-2,4 hence clarified
