What is the quotient?

Answer:
B)
Step-by-step explanation:
Here we have to divide 7x^2 - 3x - 9 by (x - 1).
Step 1: We need to get rid of 7x^2 that is the leading coefficient.
We need to add 7x in the quotient part and multiply with (x -1 )
7x(x - 1) = 7x^2 - 7x
Now we have to subtract.
Step 2: We got dividend is 4x - 9
Now we have to get rid off 4x, so we have to add +4 in the quotient part and multiply with (x -1)
4(x -1) = 4x - 4
Now we have to subtract
So we got the quotient = 7x + 4 and the remainder is -5
The answer is = 7x +4 -
Herewith I have attached the division figure.

Answer:
option C
Step-by-step explanation:
f(x)=-0.08x(x^2-11x+18)
Factor the parenthesis and find out the x intercepts
(x^2-11x+18)
We find out two factors whose product is 18 and sum is -11
-9 and -2 gives us product 18
-9 -2 gives us sum -11
(x^2-11x+18) =(x-9)(x-2)
f(x)=-0.08x(x^2-11x+18)
f(x)= -0.08x(x-9)(x-2)
set f(x) =0 and solve for x
-0.08x(x-9)(x-2) =0
-0.08x =0, so x=0
x-9 = 0 , so x=9
x-2 =0 , so x=2
x intercepts are (0,0) (2,0) and (9,0)
x intercepts are not repeating
so the graph crosses x -axis at x=0, 2,9
option C is correct
