Can the expression 21x^{2} + 74x + 11 be factored?

If so, factor it. To give your answer for this question, write the values for k, l, m and n, where k, l, m and n are constants in the factored expression (kx + m)(lx + n), and k has a greater absolute value than l (this doesn’t apply if both k and l are equal).

If there are no factors, write “N” for all values.

k =

l =

m =

n =
