    Answer:

    (3x+1)(2x+5)

    Step-by-step explanation:

    The correct expression is 2x+6x^2+5+15x

    To use the grouping method, we need to group factorable monomials using parentheses. Notice that 2x and 6x² have a common factor 2x; similarly, 5 and 15x have a common factor 5. We can group each pair of monomials using parenthesis, and then factor each one.

    2x + 6x^2 + 5+15x

    (6x^2+2x)+(15x+5)

    2x(3x+1)+5(3x+1)

    Now we can factor the common monomial (3x+1):

    (3x+1)(2x+5)
