Answer 2

Identify the number that needs to be added to both sides of the equation x^2-10x=-24 to complete the square.


okay...what does it even mean by "complete the square"?? do I just solve for x or what?

Answer 3

it means basically , make it so you can factor it

Answer 4

x^2 - 10x + ___ = -24

A = 1
B=-10

take half of B and square it

Answer 5

OH! I can factor it!!! but can I move -24 to the other side of the equation?

Answer 6

i think it doesn't want you to do that.
keep it how it is, and complete the square on the left side

Answer 7

the term to add to both sides is
\[[\frac{ B }{ 2 }]^2\]

Answer 8

okay. So take have of b...-5 and square it? that isn't a whole number though.

Answer 9

right, (-5)^2 = 25

add 25 to both sides

Answer 10

Oh. that makes so much more sense. so it ends up to be 1=1

Answer 11

sorry -1=1

Answer 12

so the number is 25 that needs to be added to both sides?

Answer 13

x^2 - 10x + 25 = -24 + 25

Answer 14

then the left can turn into
(x-5)^2

Answer 15

completed the square

Answer 16

k. now one more? real fast. last one that's giving me a hard time.
