In my homework, I'm supposed to factor the expression x^2 + 8x - 9 using the guess and check method. I know that that means I have to find two numbers that add up make the second term and multiply to make the third term. But I can't think of any numbers that add up to 8 and multiply to -9. I don't know what to do now.

factors of 9 are 1 ,3 9 what two number would you multiply to get -9 but when u add/subtract them you should 8
Nnesha
  • Nnesha
guess and check so play with signs one of the number suppose to be negative
quickstudent

Wait, in the guess and check method you can subtract also?
Nnesha
  • Nnesha
yes you can you can add or subtract both numbers to get the middle term (b which is 8 in this equation )

Oh I got it! -1 and 9. -1 + 9 = 8, and -1 * 9 = -9

So the factors should be: (x - 1) (x + 9) Correct?
Nnesha

right leading coefficient is one so you can write it as (x + (1st number)) (x+ (2nd number)) good job! :=)
