Question

can someone please help!!

Answer 1

can you please explian how to rewrite an equation in vertex form

Answer 2

you mean like a quadratic equation?

Answer 3

Post an actual problem. Easier to explain that way

Answer 4

yes i mean quadratic equation @binarymimic ... y=x^2 - 6x=4 @chaguanas

Answer 5

y = x^2 - 6x - 4 ?

Answer 6

its one of the problems i need help with .....

Answer 7

you wrote "y = x^2 - 6x = 4" but did you mean "y = x^2 - 6x - 4 "

Answer 8

oh sorry its +4

Answer 9

y = x^2 - 6x + 4

to write it in vertex form you have to complete the square. have you done that before ?

Answer 10

Do you know how to do that thing called 'completing the square'?

Answer 11

Nope

Answer 12

keep x^2 - 6x on one side,and everything else on the other so you have:

x^2 - 6x = y - 4

this just makes the process clear

then you take -6 divided by 2 = -3
take -3 and square it = 9

so add 9 to both sides

x^2 - 6x + 9 = y - 4 + 9

the left side factors now into

(x - 3)^2 = y + 5

then subtract 5 back to the left side

(x - 3)^2 - 5 = y

Answer 13

some info on how to complete the square:

Answer 14

so would that be the answer? or do i have to do more

Answer 15

y = (x - 3)^2 - 5
is the vertex form

Answer 16

okay thanks ....
