The quarratic polynomial p(x) =ax2+bx+c has two diffrent roots including -2.The quadratic polynomial q(x)=ax2 +cx+b has two diffrent roots including 3.if f&g r d other roots of p(x) and q(x) resp. then find the value of f/g
Given, quadratic polynomial are p(x) = ax2 + bx + c and q(x) = ax2 + cx + b.
The roots of p(x) are -2 and f whereas the roots of q(x) are 3 and g.
Taking p(x) = ax2 + bx + c, we get
Product of roots = -2 × f =
⇒ f = ...... (1)
Similarly, on taking q(x) = ax2 + cx + b, we get
⇒ Product of roots = 3 × g =
⇒ g = ....... (2)
On dividing (1) by (2), we get
