SOLUTION: how do you evaluate algebraic expressions?
Examples:
n2- 25 = ?
^^ the two next to the n is the squared symbol, so the equation is really:
n-squared minus twenty five

Could you please answer my first question and the equation?
Thanks! Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! write it:
n^2 - 25 = 0
add 25 to both sides and you have
n^2 = 25
n =
n = +5
and
n = -5
:
Check replace n with 5:
5^2 - 25 = 0
and
replace n with -5
(-5)^2 - 25 = 0
