Write the quadratic function in vertex form.


y = x2 - 14x + 53

Ay = (x - 7)2 - 4

By = (x + 7)2 - 4

Cy = (x - 7)2 + 4

Dy = (x + 7)2 + 4

Verified Answer :

apologiabiology

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
