Answers: x = 7/10 and x = -7/10</h3>
Explanation:
To find those results above, we apply the square root to both sides. Don't forget about the plus/minus.
x^2 = 49/100
x = sqrt(49/100) or x = -sqrt(49/100)
x = 7/10 or x = -7/10
We can confirm these answers by plugging them back into the original equation. Note that (-7/10)^2 = (-7/10)*(-7/10) = 49/100. The two negatives cancel.
