Answer 2

Answer:

Step-by-step explanation:

Case 1:  x<0⟹|x|=−x  

∴x2−3x+2=0  

(x−1)(x−2)=0  

x=1,2  

but  x<0  hence both the values of x are discarded

Case 2:  x≥0⟹|x|=x  

∴x2+3x+2=0  

(x+1)(x+2)=0  

x=−1,−2  

but  x≥0  hence both the values of x are discarded

Hence, there is no real solution for given equation:  x2+3|x|+2=0
