The answer is on the screenshot

Step-by-step explanation:

The steps are also in 2nd screenshot and is on the website, just type in the thing you need solved. Hope i helped :)

Step-by-step explanation:

factor further

and as you put it:

in the instructions, it says that 1 is a zero.

this is because when x=1

you will see that the first section (x-1) will be (1-1) which is 0

when you multiply 0 by anything, it is 0

so the entire thing would then be zero

(x-1) can not be factored further

but can

factor into  

use quadratic formula

then put it back into equation

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
