Can somebody help me find the zeroes for this, algebraically?

To solve this algebraically, you can first factor out a 3:
3(x^2-2x-8)

Then, you can factor (I'm using guess and check) and my answer is -4 and 2:3(x-4)(x+2)

From here on, finding 0s is very easy. You just solve for x in the parentheses. So, the 0s are when x = 4, and x = -2. Remember, (4-4) = 0, and (-2+2) = 0, that's what you want.

a vacation home in orlando florida, rents for $105 per day. The function f(x)=105x gives the cost of renting the home for x days
aleksley [76]
I believe the slope should be 105. In this situation in particular, 105 stands for the amount of money that is charged for the rent of a house over a period of days. Every day, $105 is added to the rental fee.

I hope this helps! ^^
