Question

How do you factor this problem?

x^2-6x+8

Answer 1

Quadratic formula.

Answer 2

Make the coefficients A, B, C respectively
Multiply A & C together, in this case it is 8
Think of factors that multiply to give you 8 and add together to get B (in this case -6)
-2 and -4 multiply to give positive eight, and add to give -6 so those are your factors
Now simply write (x-2)(x-4)

This process should work every time.

Answer 3

No need for quadratic formula, ehuman basically told you how to solve most of these problems lol.

Answer 4

Thank you everyone!!
