Equation
w² + 13w + 42 = 0
Process
1.- Find the prime factors of 42
42 2
21 3
7 7
1
42 = 2 x 3 x 7
2.- Combine the prime factors to find to numbers that added gives + 13
(2 x 3) + 7
6 + 7 = 13
This numbers are 6 and 7
3.- Factor the equation using two sets of parentheses and the square root of the first term and the previous numbers (step 2).
(x + 6)(x + 7)
