Solve the following equation.
4.7 = 1.13x^2
Do i square root the 1.13x^2 first? or divide both sides by 1.13?
Please excuse my dear aunt sally
Both will work, but it is customary to divide both sides by 1.13, which avoids an extra square-root:
haha sorry. i didn't bother to read the entire thing. you must divide first in order to root both sides
