Solve x^27x-7=0 - ScanMath

Evaluate

x^{2} \times 7 x - 7 = 0

Multiply

More Steps

7 x^{3} - 7 = 0

Move the constant to the right-hand side and change its sign

7 x^{3} = 0 + 7

Removing 0 doesn't change the value,so remove it from the expression

7 x^{3} = 7

Divide both sides

\frac{7 x ^{3}}{7} = \frac{7}{7}

Divide the numbers

x^{3} = \frac{7}{7}

Divide the numbers

More Steps

x^{3} = 1

Take the 3 -th root on both sides of the equation

3 x^{3} = 31

Calculate

x = 31

Solution

x = 1
