**Answer:**

(SS,SG,GS,GG) Probability 0.25

**Step-by-step explanation:**

i don't know how to do this

**Answer:**

6x^2 - 19x + 10 is the answer

**Step-by-step explanation:**

**Lets use the FOIL method to expand,**

(2x - 5)(3x -2)

2x * 3x + 2x * -2 + -5 * 3x + -5 * -2

This is the expanded version of the expression above!

here is a better way of explaining it,

(2x - 5) is the first equation now lets split it up

now its 2x and -5!

now you just multiply 2x and -5 to the second equation (3x - 2)

makes sense?

**Lets Simplify it,**

2x * 3x + 2x * -2 + -5 * 3x + -5 * -2

6x^2 - 4x - 15x + 10

6x^2 - 19x + 10

(tip: **DON'T FORGET SAY ^2 because there are 2x's in the (2x*3x) part!)**

Now you just simplify!

So as a result the answer is,

**6x^2 - 19x + 10**

Hope this helps :)
