Question

Find all real solutions of the equation x^2-125=0.

x_1 = ___ and x_2 = ____ with x_1 13 years ago

Answer 1

First add 125 to both sides then x^2 = 125.
Then use a radical on both sides which gives you 5 radical 5. This can be plus or minus 5radical5

Answer 2

Thanks!

Answer 3

\[x^{2}-\left( 5\sqrt{5} \right)^{2}=0,\left( x+5\sqrt{5} \right)\left( x-5\sqrt{5} \right)=0\]
from the two find x
