2x^(2) = 200
Divide both sides by '2'
Hence
x^(2) = 100
Square Root both sides
x = +/-10 The answer.

2x2 = 200
Divide both sides by 2: x2 = 100
Take square roots of both sides: x = -10 or x = +10
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
-34
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
2x-3=9 so 2x=12 and x=6
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
