Factor the expression 16x2 – 49 by using the difference of two squares method.
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).
k =
l =
m =
n =
