Question
Solve the equation
u1=−2,u2=0,u3=2
Alternative Form
u1≈−1.414214,u2=0,u3≈1.414214
Evaluate
u×1×u3=2u2
Multiply the terms
More Steps

Evaluate
u×1×u3
Rewrite the expression
u×u3
Use the product rule an×am=an+m to simplify the expression
u1+3
Add the numbers
u4
u4=2u2
Move the expression to the left side
u4−2u2=0
Factor the expression
u2(u2−2)=0
Separate the equation into 2 possible cases
u2=0u2−2=0
The only way a power can be 0 is when the base equals 0
u=0u2−2=0
Solve the equation
More Steps

Evaluate
u2−2=0
Move the constant to the right-hand side and change its sign
u2=0+2
Removing 0 doesn't change the value,so remove it from the expression
u2=2
Take the root of both sides of the equation and remember to use both positive and negative roots
u=±2
Separate the equation into 2 possible cases
u=2u=−2
u=0u=2u=−2
Solution
u1=−2,u2=0,u3=2
Alternative Form
u1≈−1.414214,u2=0,u3≈1.414214
