Am not sure if I got the answers right can you explain this to me please

So you have the multiplication and substitution right. It's just the subtraction.

Step-by-step explanation:

Now, the equation was y = 4x - 2

In the first one x = -3

So it will be 4(-3) - 2

Note: Anytime you see a bracket it means multiplication.

4× -3 = -12 and

-12 - 2 = -14

This is because a negative number minus another number is always negative.

And when dealing with negative numbers you add them but you negate the answer.

For example;

The second one will be -8 - 2

And 8 + 2 = 10

But since the numbers are negative we just negate the 10 making it - 10.

I hope this helps

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
