Simplify 3/4 - 4 z + 5/4 z - 1/2 + 1/2 z enter your answer in the box.

PLEASE HELP RIGHT AWAY :(

3/4 - 4 z + 5/4 z - 1/2 + 1/2 z

First, put the like terms together:

-4z + 5/4z + 1/2z + 3/4 - 1/2

Find the LCM of the first three to turn them into one massive fraction:

-16/4z + 5/4z + 2/4z + 3/4 - 1/2

Do the same for the last 2 fractions:

-16/4z + 5/4z + 2/4z + 3/4 - 2/4

Simplify everything (keeping like terms in mind)

-9/4z + 1/4

And that's the answer :)

(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
