Evaluate
x2=2x−3
When the expression in absolute value bars is not negative, remove the bars
x2=2x−3
Move the expression to the left side
x2−(2x−3)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x2−2x+3=0
Substitute a=1,b=−2 and c=3 into the quadratic formula x=2a−b±b2−4ac
