Answer:

Find the factors of c that add up to b.

Step-by-step explanation:

For example, if you were factoring

x^2 + 12x + 35

a=1

b=12

c=35

In order to factor, we're looking for what multiplies to 35, and adds up to 12. What multiplies to 35 are the factors of 35. In this case its 5 and 7.

5 × 7 = 35

5 + 7 = 12

So you could factor

x^2 + 12x + 35

= (x + 5)(x + 7)
  • If a equation be ax^2+bx+c

Leading coefficient=a=1

So

the equation becomes

  • x^2+bx+c
  • Now find the factors of c that can add up to b

Usually we find factors of ac but as a is 1 so it yields c only
