What is this expression in factored form?
x^2+13x+42

Answer and explanation:

(x + 6)(x + 7)

List the multiples of 42

42: 1  2  3  6  7  14  21  42

Then see which of the multiples add up to 13

1 x 42 = 42 --> 1 + 42 13

2 x 21 = 42 --> 2 + 21 13

3 x 14 = 42 --> 3 + 14 13

6 x 7 = 42 --> 6 + 7 = 13
