Question

find a quadratic polynomial whose zeros are -2 and -5 verify the relationship between zero's and coefficients of the polynomial

Answer 1

by the equation we can verify the equation

Answer 2

Answer:

Quadratic polynomial will be x^2+7x+10

Step-by-step explanation:

let the zeroes are $ and @,

so $+@=-7 and $@= 10 .

we know that form of quadratic polynomial is x^2-($+@)+$@

putting values

so the equation will be x^2+7x+10

RELATIONSHIP:

$+@=-b/a=-7/1=-7

and @$ =c/a = 10/1=10

so this is your answer .

AND SORRY OF THESE SIGNS @ and $ . In place of these you can let alpha and beeta ...
