whats the answer of this Q.

Answer 1

Answer:

p=1, q=7

Step-by-step explanation:

a²-1 is a factor of this equation, that means (a+1)(a-1) will divide this equation completely.

using remainder theorm, a=1 and a=-1 should be roots of the equation.

putting a=1

p-7+9+q-10=0

p+q=8...EQ1

putting a=-1

p+7+9-q-10=0

p-q=-6...EQ2

From EQ1 and EQ2

p=1, q=7
