Use FOIL and simply, First times First, Outside times Outside, Inside times Inside, Last times Last.
(3x+5)(4x-1)
3x * 4x = 12x²
3x * -1 = -3x
5 * 4x = 20x
5 * -1 = -5
12x² - 3x + 20x - 5
Now simplify by adding -3x to 20x and get:
12x² + 17x - 5
Associative property is a+(b+c)=(a+b)+c
step1 is commutative property of addition
2nd step is associative property of addition
3rd step is distributive property
4th step is mutliplication or associative property of multiplication
