(x-3)(x-3) simplify.
x * x + x * 3 -3 * x - 3 * 3 then solve that Does this make sense?
so... x^2 + 3x - 3x - 9 ?
You can solve that even further. 3x - 3x. so x^2 - 9
once again you can use the FOIL method. do you remebber it?
..so i think i would combine the like terms
(x-3)(x-3) x * x = x^2 x * -3 = -3x -3 * x = -3x -3 * -3 = +9 so: x^2 - 3x - 3x + 9 Then: x^2 -6x + 9 which is: (x -3)(x-3)
(x-3)(x-3) x^2-3x-3x+9
x^2 + 6x - 9....?
then your final answer is x^2-6x+9, which can be factored back into (x-3)(x-3), just like @some_someone just mapped out here
no the 9 is positive because two negatives equal a positive number
a negative - a negative = a negative a negative * a negative = a positive
right! @some_someone a negative multiplied by a positive is negative
lol yup Jamie, i was just pointing it out for Jennifer :)
Oh, oops. I didn't see that other negative sign.
so i did it wrong...or?
x^2-6x+9 is the final answer? does that make sense @jenniferjuice ? if it doesn't what questions do you have about it
Well Jenifer, you first said: x^2 + 6x - 9 But if was x^2 - 6x + 9
it was close but you have to be particular with your negatives
okay so.... x * x + x * 3 +3 * x - 3 * 3 then, x^2 + 3x + 3x - 9 then, x^2-6x+9
nope
x^2-9 = (x + 3)(x - 3)
not quite @zzr0ck3r
woops lol
its been a long say I should take a break after that note:)
