pooja195 (pooja195):

What numbers multiply to make -6 but add to make 1?

OpenStudy (anonymous):

That makes no sense, there is no numbers

pooja195 (pooja195):

Yes there is think of factors....

pooja195 (pooja195):

Think of factors of 6

OpenStudy (anonymous):

3 2 1 ?

OpenStudy (anonymous):

and 6

pooja195 (pooja195):

3 x 2 = 6 right? so what can we do so that it would equal -6?

OpenStudy (anonymous):

-3 * 2

OpenStudy (anonymous):

or 3* -2

pooja195 (pooja195):

Right but which one can multiply to make -6 AND can add/subtract to make 1?

OpenStudy (anonymous):

I still don't get it

OpenStudy (anonymous):

is it just 1?

pooja195 (pooja195):

ok 3 *2 = 6 right? but 3+2 make 5 not 1 -3 * 2 = -6 right? -3+2 make -1 not 1 that leaves us with 3*-2

OpenStudy (anonymous):

and 3-2 is 1 ohhhhh

pooja195 (pooja195):

yes :) so now we need to but it in the answer form they want so whats the answer?

OpenStudy (anonymous):

B

pooja195 (pooja195):

Yep good job :)

OpenStudy (anonymous):

THANKYOU!! minf helping me with somemore?

pooja195 (pooja195):

I can try! :)

OpenStudy (anonymous):

ok hold on

OpenStudy (anonymous):

Factor the polynomial. x2 - 6x + 9 A) (x - 9)(x - 1) B) (x - 3)(x + 3) C) (x + 9)(x + 1) D) (x - 3)(x - 3) E) (x - 9)(x + 1)

pooja195 (pooja195):

Again |dw:1441128779109:dw|

pooja195 (pooja195):

What numbers multiply to make 9 but add/subtract to make -6?

OpenStudy (anonymous):

3*3 is 9 and 3-9 would be 6
