Question

x+square root of x=12

Answer 1

That's not even the right question Kushash..

Answer 2

\[x+\sqrt{x}=12\]

Answer 3

\[\sqrt{x}=12-x=>(\sqrt{x})^2=(12-x)^2=>x=144-24x+x^2\]

Answer 4

1 subtract x from both side
2 square both side

Answer 5

my thingy got cut off

Answer 6

Multiple lines is easier to read.

Answer 7

do i factor 0=x^2-24x+144

Answer 8

yes,

Answer 9

what add up to -24 and multiplies to 144?

Answer 10

kushash.. That is not the right problem. Seriously. Stop spamming.

Answer 11

kushashwa is half right. x can be 9. he put the answer for root(x).

Answer 12

i think it should be -25x in the middle

Answer 13

thats what i thought monkey

Answer 14

because you still have that other x on the left side

Answer 15

You can either factor it, or use the quadratic equation.

Answer 16

right and if you subract that x on both sides
you have -24x-x

Answer 17

in which case it is 0=x^2-25x+144 which makes it more difficult

Answer 18

x^2-24x-x+144=0

Answer 19

so then i should use the quadratic equation to solve?

Answer 20

you can do factoring

Answer 21

(x-9)(x-16)=0

Answer 22

x = 9,16

Answer 23

you guys are awesome thank you

Answer 24

If it is something you cannot factor easily, using the quadratic formula always works. Even if it's factorable, sometimes you can't figure it out.
