Question
Solve the equation
x=35
Alternative Form
x≈1.709976
Evaluate
x2×4x−20=0
Multiply
More Steps
Evaluate
x2×4x
Multiply the terms with the same base by adding their exponents
x2+1×4
Add the numbers
x3×4
Use the commutative property to reorder the terms
4x3
4x3−20=0
Move the constant to the right-hand side and change its sign
4x3=0+20
Removing 0 doesn't change the value,so remove it from the expression
4x3=20
Divide both sides
44x3=420
Divide the numbers
x3=420
