Question
Solve the equation
x1=0,x2=27
Alternative Form
x1=0,x2=3.5
Evaluate
8×4x4=7x3
Cancel out the common factor 4
2x4=7x3
Add or subtract both sides
2x4−7x3=0
Factor the expression
x3(2x−7)=0
Separate the equation into 2 possible cases
x3=02x−7=0
The only way a power can be 0 is when the base equals 0
x=02x−7=0
Solve the equation
More Steps
Evaluate
2x−7=0
Move the constant to the right-hand side and change its sign
2x=0+7
Removing 0 doesn't change the value,so remove it from the expression
2x=7
Divide both sides
22x=27
Divide the numbers
x=27
x=0x=27
Solution
