Question 463547

{{{ 7x^2 + 4x = 3}}}

{{{ 7x^2 + 4x - 3=0}}}

*[invoke quadratic_formula 7, 4, -3, "x"]


so, solutions are {{{x=3/7}}} or {{{x=-1}}}

check if

I. The sum of the solutions is positive.

{{{3/7+(-1)=3/7-1=0.43-1=-0.57}}} 


II. The product of the solutions is negative.

{{{(3/7)(-1)=-3/7}}} 


III. Both solutions are integers. 

no, only one solution is integer


answer:

b) II only
