Answer: 6/5 and -6/5

Step-by-step explanation: In order to solve this problem, we want to get the variable on one side. In order to do that, we must do the following:

Add 36 on Both Sides:

[tex]25x^2 - 36+36 = 0+36[/tex]

Divide 25 on Both Sides:

[tex]\frac{25x^2}{25}= \frac{36}{25}[/tex]

Take the square root of Both Sides:

[tex]\sqrt{x^2} = \sqrt{\frac{36}{25} }[/tex]

That means your answer is:

[tex]x = \frac {6}{5}[/tex], or [tex] -\frac {6}{5} [/tex]
