Answer 1

Answer:

Sorry I don't know this one

Answer 2

Given that : x+a is a factor of given polynomial then, for the value of x = -a solution of polynomial will be zero

${( - a)}^{2} + p( - a) + q = 0 \\ \\ = > {a}^{2} - ap + q = 0.....(1)$

And,

${( - a)}^{2} + m( - a) + n = 0 \\ \\ = > {a}^{2} - ma + n = 0...(2)$

Form equation (1) and (2) :

${a}^{2} - pa + q = {a}^{2} - ma + n \\ \\ = > ma - pa = n - q \\ \\ = > a(m - p) = n - q \\ \\ = > a = \frac{n - q}{m - p}$

HENCE PROVED ✔️✔️
