Solve l^2232-25 - ScanMath

Question

Simplify the expression

232 l^{2} - 25

Evaluate

l^{2} \times 232 - 25

Solution

232 l^{2} - 25

Show Solution

l_{1} = - \frac{5 58}{116}, l_{2} = \frac{5 58}{116}

Alternative Form

l_{1} \approx - 0.328266, l_{2} \approx 0.328266

Evaluate

l^{2} \times 232 - 25

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

l^{2} \times 232 - 25 = 0

Use the commutative property to reorder the terms

232 l^{2} - 25 = 0

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

232 l^{2} = 0 + 25

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

232 l^{2} = 25

Divide both sides

\frac{232 l ^{2}}{232} = \frac{25}{232}

Divide the numbers

l^{2} = \frac{25}{232}

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

l = \pm \frac{25}{232}

Multiply the terms

116

\frac{5 58}{116}

l = \pm \frac{5 58}{116}

Separate the equation into 2 possible cases

l = \frac{5 58}{116} l = - \frac{5 58}{116}

Solution

l_{1} = - \frac{5 58}{116}, l_{2} = \frac{5 58}{116}

Alternative Form

l_{1} \approx - 0.328266, l_{2} \approx 0.328266
