Question

Worte a quadratic polynomial
whose
Zeroes are 5 and -8​

Answer 1

Step-by-step explanation:

the quadratic polynomial that has zero of 5 is

-x^2+2x+15

-x^2+2x+15

f(x)= -x^2+2x+15

f(5)= (-5)^2+2(5)+15

-25+10+15

-15+15

0

the quadratic polynomial that has zero of 8 is

-x^2 + 8x

f(x)= -x^2 + 8x

f(8)= (-8)^2 + 8(8)

-64+64
