Answer:
She rewrote the problem without parentheses: x3+ 2x2 - x + x3 – 2x2 +6
Step-by-step explanation:
It looks like she didn't fully distribute the -
(x3 + 2x2 - x)-(-x3 + 2x2 + 6) :Original
x3+ 2x2 - x + x3 – 2x2 +6 :Changed
~
(x3 + 2x2 - x)-(-x3 + 2x2 + 6)
x3 + 2x2 - x + x3 - 2x2 - 6
x3 + x3 + 2x2 - 2x2 -x - 6
2x3-x-6
I hope this helps ^-^
I can’t fit The Who picture but this is all I have But you could check my answer I going to answers.com which will be much more accurate than the App we are on right now

Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to

where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have

we have

The leading coefficient is negative, that means the parabola open downward
The zeros of the function are

Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)
