Solve 3d^2-22 - ScanMath

Evaluate

3 d^{2} - 22

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

3 d^{2} - 22 = 0

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

3 d^{2} = 0 + 22

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

3 d^{2} = 22

Divide both sides

\frac{3 d ^{2}}{3} = \frac{22}{3}

Divide the numbers

d^{2} = \frac{22}{3}

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

d = \pm \frac{22}{3}

Simplify the expression

More Steps

d = \pm \frac{66}{3}

Separate the equation into 2 possible cases

d = \frac{66}{3} d = - \frac{66}{3}

Solution

d_{1} = - \frac{66}{3}, d_{2} = \frac{66}{3}

Alternative Form

d_{1} \approx - 2.708013, d_{2} \approx 2.708013
