Question

I will give medals
what is the value of z so that -9 and 9 are both the same solutions of x^2 + z = 103

A. -22
B. 3
C. 22
D. 184

Answer 1

if 9 ,-9 is for x
then ovs
f(9)=f(-9) :D

Answer 2

whats the answer

Answer 3

is it 22

Answer 4

well make
f(9)=0
i thought somone was solving it O.O

Answer 5

im confused

Answer 6

since 9,-9 arw solutions then
f(9)=0

Answer 7

but that's not a option

Answer 8

yep its option
f(x)=x^2+z-103
f(9)=9^2+z-103=0
z=-22

Answer 9

yep
