WebExample: 2x2 + 7x + 3 ac is 2×3 = 6 and b is 7 So we want two numbers that multiply together to make 6, and add up to 7 In fact 6 and 1 do that (6×1=6, and 6+1=7) How do we find 6 and 1? It helps to list the factors of ac= 6, and then try adding some to get b= 7. Factors of 6 include 1, 2, 3 and 6. Aha! 1 and 6 add to 7, and 6×1=6. Web4.
