Question

if (x+y) is a factor of the polynomials x square +p x+q and x square +mx+n then prove that a =n-q/m-p
​

Answer 1

Step-by-step explanation:

(-a)² + p(-a) + q = 0 --> a² -ap + q = 0 

(-a)² + m(-a) + n = 0 --> a² -am + n = 0 

Since they both equal 0, you can set them equal to each other: 

a² -ap + q = a² -am + n 

-ap + q + -am + n 

am - ap = n-q 

a(m-p) = n-q 

or a=n-q/m-p
