Answer:
[tex]\frac25[/tex] and [tex]-\frac25[/tex]
Step-by-step explanation:
Hello!
The square root method is the process of square rooting both sides of the equation.
Solve for x
- [tex]25x^2 = 4[/tex]
- [tex]\sqrt{25x^2} = \sqrt4[/tex]
When you square root a number that is being squared (x^2), it is the absolute value of that number. Meaning that you keep a plus or minus sign on the other side.
- [tex]\sqrt{25x^2} = \sqrt4[/tex]
- [tex]5x = \pm 2[/tex]
- [tex]x = \pm \frac25[/tex]
The roots of the equation are [tex]\frac25[/tex] and [tex]-\frac25[/tex].
