Question

Jenna constructs the model to represent 3 x 2 + 11 x - 4 what factors does Jenna need to model for the sides

Answer 1

we have that
y=3x²+11x-4

using a graph tool---------> to find the roots of the equation
see the attached figure

the solution is
x=-4
x=0.333----> 1/3
so
(x+4)=0
and
(x-1/3)=0---------> (3x-1)/3=0-------> (3x-1)=0
(x+4)*(3x-1)

the answer is
(3x-1) and (x+4)
