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) + (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.

`(5x^2)/(5) = (-4)/(5)`

`x^(2) = (-4)/(5)`

Step 4) Take the square root.

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

x = ±
`\sqrt (-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
