Solve 64x^2-64 - ScanMath

Evaluate

64 x^{2} - 64

To find the roots of the expression,set the expression equal to 0

64 x^{2} - 64 = 0

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

64 x^{2} = 0 + 64

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

64 x^{2} = 64

Divide both sides

\frac{64 x ^{2}}{64} = \frac{64}{64}

Divide the numbers

x^{2} = \frac{64}{64}

Divide the numbers

More Steps

x^{2} = 1

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 1

Simplify the expression

x = \pm 1

Separate the equation into 2 possible cases

x = 1 x = - 1

Solution

x_{1} = - 1, x_{2} = 1
