Use the quadratic formula to solve 3x2 + 5x + 2 = 0.

 and x=-1

Explanation:

Find solution of

To solve for x, we set the equation =0

Now we apply quadratic formula to solve for x

The value of a=3, b=5 and c=2, plug in all the values

We will get two values for x

 and  

 and x=-1

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
