The simplified fraction is 1 6\14 One and six fourteenths or 1 2\7 one and two sevenths
Sophie factored it completely while Carlos did not.
Complete factoring is achieved when all factors other than monomial factors are prime factors. Carlos' (4x + 2) can still be factored into 2(x+1).
The product of a and b would be the constant term of the trinomial
The median of the numbers would be 7.5
