Question 570512
Since -3 does not contain the variable
variable to solve for, move it to the right-hand side of the equation
equation

2x^2=3=1

A mathematical statement that says two expressions have the same value; any number sentence with an = .  by adding 3 to both sides. 

Add 1 to 3 to get 4. 
2x^2=4


Divide each term in the equation by 2

2x^2/2 = 4/2

Simplify the left side by cancelling out common factors:

A mathematical statement that says two expressions have the same value; any number sentence with an = .  by 2. 

x^2=4/2

simplify the right hand side
x^2=2

eliminate exponent by taking sqrt of both sides

so x= sqrt+/-2
