Answer 1

Answer:

$x \times x + x \times 4 + x \times x + x \times 1 - 3 \times x + 3 \times 4 + 3 \times x + 3 \times 1$

Answer 2

Answer:

D. (x-3)(x-3)(x-1)

Step-by-step explanation:

(x³-7x²+15x-9)/(x-3) = x²-4x+3 (see attached)

x²-4x+3=(x-1)(x-3) (factorisation)

∴x³-7x²+15x-9=(x-3)(x-3)(x-1)
