Robert has a reccuring deposit account in a bank. he deposits $1500 per month for 4 years. if he gets $ 1,01,250 at the time of maturity, find
• the intrest paid by the bank,
• the rate of intrest.

1)$ 65250

2)

Step-by-step explanation:

Amount Deposited in 24 months = $1500 × 24 = $ 36000

Maurity amount = $ 1,01,250

1) So, intrest paid by the bank= $1,01,250 - $65,250

2)

Sorry, I tried to do this part but I got it wrong. please forgive me, may some genious save you.

(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
