to know the nature of roots we have to calculate its discriminant value
1st equation is 4x^2+12x+9=0
a=4 b=12 c=9
discriminant= b^2-4ac
12^2-4x4x9
144-144
D=0 therefore the roots are equal and real
2nd equation is (u didnt mentioned it clearly but i think its not possible mention it clearly so that in a matter of fact manner we can do it easyly.....)
