Simon has a poster with a margin of 1 inch on all sides. The printed area is 25 square inches. He wants to determine the area of the entire poster including the margin. His work is shown. in2= 5 in 5 (side) + 1 (margin) = 6 inches Poster area = 62 = 36 in2 Which of the follow statements about Simon’s calculations are true? Check all that apply. Simon did not calculate the correct area of the poster. Simon calculated the correct area of the poster. Simon needed to find the perfect square of 7 to find the poster’s area. Simon needed to multiply 7 by itself to find the correct area. Simon needed to multiply 6 by itself to find the correct area. help me fast

(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
