Step-by-step explanation:
<span>6 * $10 + 6 * $4 = 6 * $14
It's the distributive law property - the formula is:
</span>a * b + a * c = a * (b + c)
In this situation:
a = 6
b = 10
c = 4
And 6 * $10 + 6 * $4 = 6 * $14 is the same as 6 * $10 + 6 * $4 = 6 * ($10 + $4)

Add together
9x^2 -6x+6x -4
9x^2 -4
