Question
Solve the equation
x∈/R
Alternative Form
No real solution
Evaluate
x2−23x+3=0
Move the expression to the right-hand side and change its sign
−23x=−x2−3
Divide both sides of the equation by −1
23x=x2+3
Rewrite the expression
3x=2x2+3
Raise both sides of the equation to the 2-th power to eliminate the isolated 2-th root
(3x)2=(2x2+3)2
Evaluate the power
3x=4x4+6x2+9
Cross multiply
3x×4=x4+6x2+9
Simplify the equation
12x=x4+6x2+9
Move the expression to the left side
12x−(x4+6x2+9)=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
12x−x4−6x2−9=0
Solution
