Answer 1

Answer:

$q {}^{2} - 10q + 21 \\ q ^{2} - 7q - 3q \: + 21 \\ q(q - 7) - 3(q - 7) \\ (q - 7)(q - 3) \\ q - 7 = 0 \\ q = 7 \\ q - 3 = 0 \\ q = 3$

Answer 2

Step-by-step explanation:

q^2-10q+21

q^2-7q-3q+21

q (q-7)-3 (q-7)

(q-3) (q-7)

So, the factors of the given equation is (q-3) & (q-7).
