To find the value of z, we substitute the given solutions of x into the equation and solve for z.
When x = -9, we have:
(-9)^2 + z = 103
81 + z = 103
z = 103 - 81
z = 22
When x = 9, we have:
(9)^2 + z = 103
81 + z = 103
z = 103 - 81
z = 22
Both solutions give us the same value of z = 22.
Therefore, the answer is C. 22.
what is the value of z so that -9 and 9 are both solutions of x^2 + z = 103?
