### Same as yesterday's yet this time with negatives.

all we did today was the sheets that arvin didnt finish... nice going.. and we went on to the next part of it. This time it's with a twist, there are negatives...

if the question was..

x^2 + 12x +20

it would be equal to...

(x + 2) (x+ 10) = x^2 + 10x + 2x +20 = x^2 + 12x + 20x

this time... we did it with negatives...

find the factors of..

x^2 - 12x -20

it would be equal to...

(x - 2) (x + 10) = x^2 -10x -2x -20 = x^2 -12x -20

now now now... how did i do that?

hmm.. because + times - is = (-)

:P

i guess now i did my part... so i'll leave it to that..

Remember to do that pages ms. armstrong told us to do.

the Whole page 20 i think..

CYA!!

Check your factoring with negatives. Remember:

- x - = + Even number of - gives +

+ x + = +

- x + = - Odd number of - gives -

+ x - = +
