Question

Solve the equation.

Answer 1

\[2\sqrt{x}+8-8=-2-8\]
\[2\sqrt{x}=-10\]
now what wold you do?

Answer 2

i did that... and then i found the square root x and got 2x= -10

Answer 3

no you have to do something with the 2? so what do you think?

Answer 4

i have no idea :/

Answer 5

\[2\sqrt{x}=-10\]
so since I'm multipling by 2 the I need to divide by 2 to move it to the other side
\[\sqrt{x}=-10/2\]
\[\sqrt{x}=-5\]
then square both sides
\[\left( \sqrt{x} \right)^{2}=\left( -5 \right)^{2}\]
\[x=25\]

Answer 6

did this help

Answer 7

this helped so much!!! thank you!

Answer 8

but wouldn't it be -25?

Answer 9

no because negative times negative is postive
