Question

how do you solve (√x+5)+(√x-2)=5

Answer 1

Rather,
\[\sqrt{x}+\sqrt{x}=2\sqrt{x}\]

Answer 2

@BangkokGarrett as for this question, how can we apply it? how do we solve it!??

Answer 3

@BangkokGarrett i think it has something to do with quadratic equation... please help!

Answer 4

I'll do the first couple of steps
\[\sqrt{x}+5+\sqrt{x}-2=5\]
\[2\sqrt{x}+3=5\]
Just keep going 'til you have the sqrt(x) isolated on the left of the equation

Answer 5

No need for the quadratic equation here.

Answer 6

@BangkokGarrett but i have a question, then don't you have to multiply 5 and 2 on the other side as well, meaning:

√+5+x−√−2=5x5x2 ?
