Question

Match the solution sets (complete solution sets) for the inequalities given in List 1 appropriately to those given in List 2.

Answer 1

A) $LHS>0$ but $RHS<0$
$\Rightarrow$ A matches with 4.
(B)$(x+2)(2x-1)\le 0\Rightarrow x\in [-2,\frac{1}{2}]$
$\Rightarrow$ B matches with 1.
(C)$x^2-3x+2>0\Rightarrow (x-2)(x-1)>0\Rightarrow x<1orx>2$
$\Rightarrow$ C matches with 3.
(D)$x^2-3x-4\le 0\Rightarrow (x-4)(x+1)\le 0\Rightarrow -1\le x\le 4$
$\Rightarrow$ D matches with 5.
(E)$(x+1)(x-2)<0\Rightarrow x\in (-1,2)$
$\Rightarrow$ E matches with 2.
