Set it to 0
2x² - 200 = 0
Factor out the 2
2(x² - 100) = 0
Use difference of squares
2(x + 10)(x - 10) = 0
Solve for x
x = -/+ 10
2x² - 200 = 0
Factor out the 2
2(x² - 100) = 0
Use difference of squares
2(x + 10)(x - 10) = 0
Solve for x
x = -/+ 10

Set the equation to 0 and solve for x.
2x^2 = 200
Divide both sides by 2.
x^2 = 200/2
x^2 = 100
Take square root of both sides.
x = positive 10 and negative 10
Always a positive and negative answer in terms of square roots.
Done!
