Answer:

x = -2, x = 2.25

Step-by-step explanation:

We can use factoring (splitting the middle term) to solve this:

4x^2 - 9x + 8x - 18 = 0

x(4x - 9) + 2(4x - 9) = 0

(x + 2)(4x - 9) = 0

Now we can set each factor equal to 0 using the Zero Product Property to get our final answer.

x + 2 = 0

x = -2

4x - 9 = 0

4x = 9

x = 9/4 = 2.25
