Answer:
The slope is 0.
Step-by-step explanation:
You just need to see if you can isolate the y-variable.
Take the complex zero 1+i. There must be another zero 1-i to balance it, so we have the factors (x-1-i)(x-1+i)=x²-2x+1+1=x²-2x+2.
So the polynomial is (x+3)(x²-2x+2)=x³-2x²+2x+3x²-6x+6=x³+x²-4x+6, option D.
For the given trinomial

We need to multiply a by c

We split the middle term with these two factors

To obtain,

We now factor

This implies
