Question

Solve The Equation Using Square Roots.

x(square) - 25 = 0

Answer 1

\[x^2=25\Rightarrow \sqrt{x^2}=\sqrt{25}\]From this point you can find the answer.

Answer 2

is it 5 @John_ES

Answer 3

no

Answer 4

No, you need the complete solution
\[x=\pm 5\]It has two solutions, +5 and -5.

Answer 5

how do i find the square root of x^2 lol there isnt no square root right?

Answer 6

it is true that \(5^2=25\) so if you replace \(x\) by \(5\) it will work, but it will also work if \(x=-5\) as well

Answer 7

@John_ES

Answer 8

It is easy, the square root of a square eliminates the 2 of the x.

Answer 9

is that the answer or is there more to it?

Answer 10

I mean, if you need to find the
\[\sqrt{x^2}\]
you need to find the number whose square is x^2. And this is x.

Answer 11

No, this is the complete answer. +5 and -5.

Answer 12

how is the answer suppose to look? u dont have to give me the answer just yet but i would like how the answer could look @John_ES

Answer 13

I would write the answer in this form
\[x=\pm5\]In this concrete type of problems, the left side is always the same, and the right side is the square root of a number.

Answer 14

lol thanks man i got lost because how my computer showed what u typed but i got it now its 5 is plus and minus @John_ES

Answer 15

Yes ;)
