Answer:
A
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
obtain (5 + x)(5 - x) = 7 in this form by expanding the factors
25 - x ² = 7 ( subtract 7 from both sides )
18 - x² = 0 ( multiply through by - 1 )
x² - 18 = 0 ← in standard form
with a = 1, b= 0 and c = - 18 → A
f is given as -3
-3 is greater than -4, so use the second equation 3x-5.
replace x with -3 and calculate:
3(-3) - 5 = -9 - 5 = -14
The answer is -14.
