Question 25691: I need help solving this problem solve for X.
This is how I tried to solve it, I tried two way but I am unsure
2X^2=288
(2x)(2x)=288
4X=288
X=72
Or I also tried this way
2*X^2=288
2*(X)(X)=288
2X=288
2X/2=288/2
X=144

Solve for x:
Notice that only the x is squared, not the 2. Divide both sides of the eqaution by 2.
Now take the square-root of both sides.
and + or -
x = + or - 12
