Factoring can sometimes give you easy answers to quadratics. Look at the following example: x 2 + x - 2 = 0 Now let's factor it: (x - 1)(x + 2) = 0 Now, think back to elementary multiplication. Zero times anything is equal to zero. If we ke...
9s^2 + 2s - 7 = 0 a=9 b=2 c=-7 ac=-63, now find 2 numbers which when you multiply them makes -63 and add them to be 2 the numbers are 9 and -7 so 9s^2 + 2s - 7 = 0 Now, split 2s with the number you found (9 and -7) so replace 2s with 9s-7s ...

I would say that you would generally want to put in in standard form: ax2+bx+ c, first no matter what the situation. It would make factoring easier and defines the constants a,b,&c for the quadratic equation.

Well, that depends on what you mean "solve by factoring." For any quadratic equation, it is possible to factor the quadratic, and then the roots can be recovered from the factors. So in the very weak sense that every quadratic can...

If you have ax^2+bx+c=0 and you can factor it, then you can set each factor=0 and solve. This is because multiplying two things together, if you get 0 then one of the things must be zero. For example x^2+4x+3=0. This factors as (x+1)(x+3)=0...
