There is no real solution for \( z \) in the equation \( 6z^{2}+68=1+5 \).

Solución

Solve the equation \( 6z^{2}+68=1+5 \). Solve the equation(The complex numbers system) by following steps: - step0: Solve using square roots: \(6z^{2}+68=1+5\) - step1: Add the numbers: \(6z^{2}+68=6\) - step2: Add or subtract both sides: \(6z^{2}=-62\) - step3: Divide both sides: \(\frac{6z^{2}}{6}=\frac{-62}{6}\) - step4: Divide the numbers: \(z^{2}=-\frac{31}{3}\) - step5: Simplify the expression: \(z=\pm \sqrt{-\frac{31}{3}}\) - step6: Simplify the expression: \(z=\pm \frac{\sqrt{93}}{3}i\) - step7: Separate into possible cases: \(\begin{align}&z=\frac{\sqrt{93}}{3}i\\&z=-\frac{\sqrt{93}}{3}i\end{align}\) - step8: Rewrite: \(z_{1}=-\frac{\sqrt{93}}{3}i,z_{2}=\frac{\sqrt{93}}{3}i\) - step9: Remove the complex number(s): \(\textrm{No real solution}\) The equation \(6z^{2}+68=1+5\) does not have a real solution. Therefore, there is no value of \(z\) that satisfies the equation.

First, simplify the equation first by isolating the variable term. Subtract 1 and 5 from both sides to get \(6z^2 + 68 - 1 - 5 = 0\), leading to \(6z^2 + 62 = 0\). Now, rearrange this into \(6z^2 = -62\) and divide by 6 to obtain \(z^2 = -\frac{62}{6}\), which can be simplified to \(z^2 = -\frac{31}{3}\). Now apply the square root property! It's crucial to note that \(z\) has complex solutions since we're looking at a negative value under the square root. Therefore, we'll have \(z = \pm i\sqrt{\frac{31}{3}}\). Simplifying further gives us the final answers: \(z = \pm \frac{i \sqrt{93}}{3}\). So, your results are: \[ \frac{i \sqrt{93}}{3}, -\frac{i \sqrt{93}}{3} \]
