Solve l^2174-1 - ScanMath

Evaluate

l^{2} \times 174 - 1

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

l^{2} \times 174 - 1 = 0

Use the commutative property to reorder the terms

174 l^{2} - 1 = 0

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

174 l^{2} = 0 + 1

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

174 l^{2} = 1

Divide both sides

\frac{174 l ^{2}}{174} = \frac{1}{174}

Divide the numbers

l^{2} = \frac{1}{174}

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

l = \pm \frac{1}{174}

Simplify the expression

More Steps

l = \pm \frac{174}{174}

Separate the equation into 2 possible cases

l = \frac{174}{174} l = - \frac{174}{174}

Solution

l_{1} = - \frac{174}{174}, l_{2} = \frac{174}{174}

Alternative Form

l_{1} \approx - 0.07581, l_{2} \approx 0.07581
