Solve 3-4F^2 - ScanMath

Evaluate

3 - 4 F^{2}

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

3 - 4 F^{2} = 0

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

- 4 F^{2} = 0 - 3

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

- 4 F^{2} = - 3

Change the signs on both sides of the equation

4 F^{2} = 3

Divide both sides

\frac{4 F ^{2}}{4} = \frac{3}{4}

Divide the numbers

F^{2} = \frac{3}{4}

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

F = \pm \frac{3}{4}

Simplify the expression

More Steps

F = \pm \frac{3}{2}

Separate the equation into 2 possible cases

F = \frac{3}{2} F = - \frac{3}{2}

Solution

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

Alternative Form

F_{1} \approx - 0.866025, F_{2} \approx 0.866025
