The given x^3+2x^-2+ 4/x+5 expression is not a polynomial as it contains negative exponents and denominator variables. and some integer. Find the slope m of the tangent to the curve y = 5/ x at the point where x = a > 0. and as we knowthat two root of an equation are b + root 4ac / 2a and b root 4acThusAnother root. This is a polynomial, since we can easily separate the terms in the numerator and rewrite it as: Although each coefficient is a fraction, the powers of x are all whole numbers: 2 for the first term, 1 for the second term, and zero for the third term. The roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots. If $a+\sqrt b$ is a root of $p (x)$, then $q (\sqrt b)=p (a+\sqrt b)=0$.
