A) 4
B) 3
C) 2
D) 1
Correct Answer: A
Solution :
Given equation \[{{x}^{2}}-5|x|+6=0\] i.e., \[{{x}^{2}}-5x+6=0\] and \[{{x}^{2}}+5x+6=0\] \[{{x}^{2}}-3x-2x+6=0\] and \[{{x}^{2}}+3x+2x+6=0\] \[(x-3)\,(x-2)=0\] and \[(x+3)\,.\,(x+2)=0\] \[x=3,x=2\] and \[x=-3,\,x=-2\]. i.e., Four solutions of this equation.You need to login to perform this action.
