Question
Solve the equation
w1=0,w2=18
Evaluate
(18−w)×2w4=0
Multiply the terms
2w4(18−w)=0
Elimination the left coefficient
w4(18−w)=0
Separate the equation into 2 possible cases
w4=018−w=0
The only way a power can be 0 is when the base equals 0
w=018−w=0
Solve the equation
More Steps

Evaluate
18−w=0
Move the constant to the right-hand side and change its sign
−w=0−18
Removing 0 doesn't change the value,so remove it from the expression
−w=−18
Change the signs on both sides of the equation
w=18
w=0w=18
Solution
w1=0,w2=18
