1st one jus did this
Step-by-step explanation:
easy
For this case we have a quadratic equation,
, of the form 
Where:

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.
These numbers are:

Then, the factorization is given by:

The roots are:

Answer:

(x-3)(6x-2)
x*6x + x*(-2) -3*6x (-2)*(-3)
6x^{2} -2x-18x+6
6x^2-20x+6
I would say it's H because 4 and 3 add to be 7
