Question

Factor completely: −7x2 + 14x − 21

−1(x2 − 14x + 21)

−7x(x2 − 2x + 3)

−7(x2 + 2x − 3)

−7(x2 − 2x + 3)

Answer 1

Factor out a like term from the equation

Answer 2

-308

Answer 3

What is the like term you see in the expression?

Answer 4

-7*2+14*-21

Answer 5

Lol -308 though^^

Answer 6

fuuny

Answer 7

@jenniferjuice have you figured out the answer yet?

Answer 8

not really :/

Answer 9

Ok if we look at the expression given we can see the coefficients are 7, 14, and 21. Now we know what these 3 have in common is that they are divisible by 7. So the 1st thing we see is that we can factor out a -7

Answer 10

You understand so far?

Answer 11

The next thing you must do is look at the choices of answers you are given...the only two that old be possibly right are the last two

Answer 12

Could*

Answer 13

Next you have to look at the operators(signs) if we factored out a -7 then we have to see which answer when distributed will give us -7x^2+14x-21

Answer 14

so would it be ... −7(x2 − 2x + 3) ?

Answer 15

The answer would be -7(x^2-2x+3) => -7x^2-14x+21

Answer 16

Lol I mean -7x^2+14x-21.....Hess your correct

Answer 17

oh okay thanks ! :)

Answer 18

Smh yes iPad keypad is messing up but last one is correct

Answer 19

haha okay :)
