Question
Solve the system of equations
x1=0,x2=2
Evaluate
{x2=x×xx×x=2x
Calculate
More Steps

Evaluate
x2=x×x
Multiply the terms
x2=x2
The statement is true for any value of x
x∈R
{x∈Rx×x=2x
Calculate
More Steps

Evaluate
x×x=2x
Multiply the terms
x2=2x
Move the expression to the left side
x2−2x=0
Factor the expression
More Steps

Evaluate
x2−2x
Rewrite the expression
x×x−x×2
Factor out x from the expression
x(x−2)
x(x−2)=0
When the product of factors equals 0,at least one factor is 0
x=0x−2=0
Solve the equation for x
More Steps

Evaluate
x−2=0
Move the constant to the right-hand side and change its sign
x=0+2
Removing 0 doesn't change the value,so remove it from the expression
x=2
x=0x=2
Calculate
x=0∪x=2
{x∈Rx=0∪x=2
Find the intersection
x=0∪x=2
