Answer 1

a)

$\frac{6x^3 + 30x^2 + 2x}{2x}\\ \frac{6x^3}{2x} + \frac{30x^2}{2x} + \frac{2x}{2x} \\3x^2 + 15x + 1$

b)

$\frac{(x^2 - 8x + 7)}{(x - 7)} \\\frac{(x + 7)(x - 7)}{(x-7)} \\(x + 7)$

c)

$\frac{(x^3 + 10x^2 + 29x + 20)}{(x^2 + 5x + 4)} \\\frac{(x) * 5(x^2 + 5x + 4)}{(x^2 + 5x + 4)} = 5 + x$
