Solve 50-150 f^2 - ScanMath

Evaluate

50 - 150 f^{2}

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

50 - 150 f^{2} = 0

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

- 150 f^{2} = 0 - 50

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

- 150 f^{2} = - 50

Change the signs on both sides of the equation

150 f^{2} = 50

Divide both sides

\frac{150 f ^{2}}{150} = \frac{50}{150}

Divide the numbers

f^{2} = \frac{50}{150}

Cancel out the common factor 50

f^{2} = \frac{1}{3}

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

f = \pm \frac{1}{3}

Simplify the expression

More Steps

f = \pm \frac{3}{3}

Separate the equation into 2 possible cases

f = \frac{3}{3} f = - \frac{3}{3}

Solution

f_{1} = - \frac{3}{3}, f_{2} = \frac{3}{3}

Alternative Form

f_{1} \approx - 0.57735, f_{2} \approx 0.57735
