anushka5965: because the write answer is -4 and 6

anushka5965: because the write answer is -4/aand 6/a

aditikaushik1410: dear mate,its a simple middle term splitting question that is easy to do yours one is little complex

anushka5965: write answer is 6/a and -4/a

aditikaushik1410: see the answer then..-_-

anushka5965: we have to find the value of x not ax

aditikaushik1410: see it correctly ,maths can be solved in many ways hope you understood mate

aditikaushik1410: see the pic correctly refresh your app

anushka5965: ax+4=0 then x=-4/a

anushka5965: now you are correct

D= (2a)^2-(-24*a^2*4)

= 4a^2+96a^2

=100a^2

X= (2a+-√D)/2a^2

= (2a+-10a)/2a^2

X = 12a/2a^2

= 6/a

and

X= (2a-10a)/2a^2

= -8a/2a^2

= -4/a

alokthelegend: I have solved it by using discriminant formula

alokthelegend: (-b+-√d)/2a

alokthelegend: d=b^2-4ac
