Grand Total: $29.81
Total Bill: $24.84
Sales Tax (8%): $1.84
Total Tip (20%): $4.97
Answer:
Step-by-step explanation:
It's two unequal real solutions.
a = 1
b = 7
c = 6
discriminate = sqrt(7^2 - 4*1*6)
discriminate = sqrt(49 - 24)
discriminate = sqrt(25)
discriminate = 5
Now you cannot determine what this means unless you put it in the quadratic formula
x = (-7 +/- 5)/2
x = (- 7 + 5) / 2
x = - 2/2 = - 1
x = (-7 - 5)/2
x = -12/2
x = - 6
You see that you have two unequal reals.

Answer:
f(x) = 4(x -1)^3·(x +2)
Step-by-step explanation:
Each root x=p indicates the function has a factor (x -p). The factor will be repeated according to the multiplicity of the root.
f(x) = a(x -1)^3·(x +2)
f(0) = a(-1)^3·2 = -2a = -8 ⇒ a = 4
The factored form of the equation is ...
f(x) = 4(x -1)^3·(x +2)
