Boxes of cereal usually cast $4,but are on sale for $1 off. A gallon of milk costs $3 . The expression 4b-1b+3 can be used to find the cost in dollars of buying b boxes of cereal and a gallon of milk. Write the expression in simpler from.

c = 3(b + 1)

Step-by-step explanation:

c = 4b - 1b + 3

4b - 1b = 3b

c = 3b + 3

3 is a common factor of both terms on the right hand side

Factorizing the expression

c = 3(b + 1)

step-by-step explanation:

(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
