Question
Solve the equation
x1=−53265,x2=53265
Alternative Form
x1≈−0.307148,x2≈0.307148
Evaluate
x20=212x
Find the domain
x20=212x,x=0
Cross multiply
20=x×212x
Simplify the equation
20=212x2
Rewrite the expression
4×5=4×53x2
Evaluate
5=53x2
Swap the sides of the equation
53x2=5
Divide both sides
5353x2=535
Divide the numbers
x2=535
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±535
