Can someone solve and show work for this pls

Dividing : 6x5 + 26x4 - 5x3 + 17x2 - 21x + 10

("Dividend")

By : 3x - 2 ("Divisor")

dividend 6x5 + 26x4 - 5x3 + 17x2 - 21x + 10

- divisor * 2x4 6x5 - 4x4

remainder 30x4 - 5x3 + 17x2 - 21x + 10

- divisor * 10x3 30x4 - 20x3

remainder 15x3 + 17x2 - 21x + 10

- divisor * 5x2 15x3 - 10x2

remainder 27x2 - 21x + 10

- divisor * 9x1 27x2 - 18x

remainder - 3x + 10

- divisor * -x0 - 3x + 2

remainder 8

Quotient : 2x4 + 10x3 + 5x2 + 9x - 1

Remainder : 8

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
