which equation represent y=x^2-10x+30 in vertex form

Answer 1

which which equation ?

Answer 2

the one that looks like: y = M(x-xo)^2 +yo

Answer 3

(x-5)^2 +30-25 if i see it right

Answer 4

y = (x-5)^2 +5 ....

just complete the square; and remember to subtract the part you add to keep theing copacetic

Answer 5

a. y=(x-5)^2+5
b. y=(x-5)^2-5
c. y=(x-5)^2+30
d. y=(x-5)^2+55

Answer 6

i believe its 'a'; you can dbl check by expanding it out again
