Simplify these expression. a.4c+9+3. b. 10x+(-4)+(-10) c.-9+3x+14. d.11y+6+(-7)

a)4c +12 b)10x + -14 c) 3x+5 d)11y+(-1)

Step-by-step explanation:

as the nos without the variables can be added we can add the integers

a. 4c + 9 + 3

Add the constants (9 + 3 = 12).

4c + 12

b. 10x + (–4) + (–10)

Add the constants [(–4) + (–10) = –14].

10x – 14

c. –9 + 3x + 14

Add the constants (–9 + 14 = 5).

3x + 5

d. 11y + 6 + (–7)

Add the constants [6 + (–7) = –1].

11y – 1

(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
