Question

Factor the following polynomial: x2 + 20x + 36
(x + 2)(x + 10)
(x + 6)(x + 6)
(x + 9)(x + 4)
(x + 2)(x + 18)

Answer 1

\[(x+a)(x+b)=x^2+(a+b)x+ab\]So, \(a\) and \(b\) need to have what sum and product?

Answer 2

To factor multiply the coefficient of the first term by the constant in the last term. Which is 36(1,2,3,4,6,9,12,18 and 36) then look for 2 factors of 36 that can add to give you 20.

Answer 3

From that being said what do you think your answer is?

Answer 4

I DO NOT KNOW

Answer 5

x^2+2x+18x+36

Answer 6

I TINK IT IS THE LAST ONE

Answer 7

Yes it is.
x(x+2)+18(x+2)
(x+2)(x+18)

Answer 8

Factor the following polynomial: x2 – 14x + 24
(x – 2)(x – 12)
(x – 2)(x + 7)
(x – 6)(x – 4)
(x – 14)(x + 1)

Answer 9

The technique here is identical.

Answer 10

IT IS STILL HARD FOR ME

Answer 11

Did you try it at least?

Answer 12

YES I GOT CONFUSED

Answer 13

What did you get?

Answer 14

I GOT STUCK IN THE PROCESS OF DOING IT

Answer 15

What numbers multiply to 24 and add to -14?

Answer 16

IS IT THE FIRST ONE

Answer 17

HELP

Answer 18

yes
