Answer 1

(14).

Given Equation is x^2 + bx + c = (x + p)(x - q)

= > x^2 + bx + c = x^2 - xq + px - pq

= > x^2 + bx + c = x^2 - (p - q)x - pq.

Here,

the value of b = p - q, c = -pq.

-----------------------------------------------------------------------------------------------------------------

Now,

= > x^2 - bxy + cy^2

= > x^2 - (p - q)xy - pqy^2

= > x^2 - pxy + qxy - pqy^2

= > x(x - py) + qy(x - py)

= > (x + qy)(x - py).

Hope this helps!
