Two square garden's are planted. The first has a side length of 12 meters The second garden has a side length of 15 meters. How many square meters greater is the area of the second than the first?​

area of first garden

:- side×side

:- 12×12

:- 144m²

area of second garden

:- side×side

:- 15×15

:- 225m²

difference between not square gardens

:- 225-144

:- 81 m²

(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
