Solve for x :

98(x)^2-231x-393= -1​​​

Answer 1

Step-by-step explanation:

98x^2-231x-393=-1

98^2-231x-392=0

by using quadratic formula

x=-b+_ √b^2-4ac/2a

=-(-231)+_√(-231)^2-4(98)(-392)/2(98)

=231+_√53361-4(38416)/196

=231+_√53361-153664/196

=231+_√-100303/196

=231+_7√2047/196

=231+_√2047/28

=231+_1.6158

x=231+1.6158 ; 231-1.6158

=232.7(opproximately) ; 229.4(opproximately)
