Q. Statement 1 : If f(x)=ax2+bx+c, where a>0,c<0 and b∈R, then roots of f(x)=0 must be real and distinct .Statement 2 : If f(x)=ax2+bx+c, where a>0,b∈R,b≠0 and the roots of f(x)=0 are real and distinct, then c is necessarily negative real num...
Cylindrical decomposition and false derivatives are used to find the number of distinct real solutions of a polynomial with integral coefficients p(x, x), where n is large. The computation time depends only poly normally on the size of the problem, where this is defined to be the maximum of...
