Question

Solve: 25x^2 - 36 = 0

Answer 1

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:

$25x^2 - 36+36 = 0+36$

Divide 25 on Both Sides:

$\frac{25x^2}{25}= \frac{36}{25}$

Take the square root of Both Sides:

$\sqrt{x^2} = \sqrt{\frac{36}{25} }$

That means your answer is:

$x = \frac {6}{5}$, or $-\frac {6}{5}$
