° ∪ ° Hi there!

Let's solve your equation step-by-step.

3  x^{2} +   \frac{4x}{2} x + 9 = 5

Step 1) Simplify both sides of the equation.

5 x^{2} + 9 = 5

Step 2) Subtract 9 from both sides.

5 x^{2}  + 9 - 9 = 5 - 9

5 x^{2} = -4

Step 3) Divide both sides by 5.

\frac{5x^2}{5} =  \frac{-4}{5}

x^{2} =  \frac{-4}{5}

Step 4) Take the square root.

(This isn't something I can write the whole thing with the pretty writing.)

x = ± \sqrt  \frac{-4}{5}

Answer -

There are no real solutions.

We, unfortunately, do not have an x since there are no real solutions.

Hope this helps! :D
