Solve l^226-1 - ScanMath

Evaluate

l^{2} \times 26 - 1

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

l^{2} \times 26 - 1 = 0

Use the commutative property to reorder the terms

26 l^{2} - 1 = 0

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

26 l^{2} = 0 + 1

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

26 l^{2} = 1

Divide both sides

\frac{26 l ^{2}}{26} = \frac{1}{26}

Divide the numbers

l^{2} = \frac{1}{26}

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

l = \pm \frac{1}{26}

Simplify the expression

More Steps

l = \pm \frac{26}{26}

Separate the equation into 2 possible cases

l = \frac{26}{26} l = - \frac{26}{26}

Solution

l_{1} = - \frac{26}{26}, l_{2} = \frac{26}{26}

Alternative Form

l_{1} \approx - 0.196116, l_{2} \approx 0.196116
