If limx→∞a(2x3−x2)+b(x3−1)−c(3x3+x2)a(5x4−x)−bx4+c(4x4+1 – InterviewSolution

1.	If limx→∞a(2x3−x2)+b(x3−1)−c(3x3+x2)a(5x4−x)−bx4+c(4x4+1)+2x2+5x=1, then the value of (a−b−c) can be expressed in the lowest form as pq where p,q∈N. The value of p+q is
Answer» If $lim x \to \infty \frac{a (2 x^{3} - x^{2}) + b (x^{3} - 1) - c (3 x^{3} + x^{2})}{a (5 x^{4} - x) - b x^{4} + c (4 x^{4} + 1) + 2 x^{2} + 5 x} = 1,$ then the value of $(a - b - c)$ can be expressed in the lowest form as $\frac{p}{q}$ where $p, q \in N .$ The value of $p + q$ is
