Answer 2

Answer:

Q 11

True, it is Rational

Q 12

We have

g(x) = a(x2 + 1) − x(a2 + 1)=

ax2 − a2x − x + a

=ax2 − (a2+1)x + a

Now, zeroes of g(x) are given by solving the equation,

   g(x) = 0⇒ax2 − a2x − x + a = 0

⇒ax(x − a) − 1(x − a) = 0

⇒(ax − 1)(x − a) = 0

⇒ax − 1 = 0   or    x − a = 0

⇒x = 1a   or  x = a

Sum of zeroes= 1/a + a = 1+a^2/a = −coefficient x/coefficient of x^2

Product of zeroes = 1/a×q= 1 = coefficient  term/coefficient of x^2
