5x * x = 5x^2
x * -2 = -2x
-3 * 5x = -15x
-3 * -2 = 6
All together, you have:
5x^2 -2x -15x + 6
You can combine the two middle terms to get:
5x^2 -17x + 6, as your answer.

F - Multiply the first two.
x * 5x = 5x^2
O - Multiply the outside two (x and -2)
x * -2 = -2x
So right now we have 5x^2 -2x
I - Multiply the inside two (-3 and 5x).
-3 * 5x = -15x
So right now we have 5x^2 -2x -15x
L - Multiply the last two (-3 and -2)
-3 * -2 = +6, since multiplying like signs is always positive!
So we have 5x^2 -2x -15x +6
add the negatives that have the same variable (x)
-2x + -15x = -17x
So the answer is: 5x^2 -17x +6
