Question

If 3x^2+4x/2x+9=5 find x

Answer 1

° ∪ ° 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
