C
Answer:
(5/2) ² or 25 /4
Step-by-step explanation:
x² - 5x - 18 = 0
x² -5x = 18
x² -5x + (5/2)²= 18 + (5/2)²
Complete the square
isolate x terms
y=(x^2-14x)+53
take 1/2 of -14 and square it ((-7)^2=49
add plus and minus of that inside the parntehasees
y=(x^2-14x+49-49)+53
factor perfect suqrae
y=((x-7)^2-49)+53
get rid of parnthasees
y=(x-7)^2-49+53
y=(x-7)^2+4
