hold on @zeinas.

Answer 3

K

Answer 4

1 : B & D
2 : A
3 : C

Answer 5

For number 1, we know that we need two numbers that multiply to -10, and add to -9. And they are -10 and +1, so
(x+10)(x-1)
So it will be A, D

Answer 6

1 : B & C
2 : C

Answer 7

what bout 2 & 3?

Answer 8

-9 = -10 + 1
-10 = -10 * 1
@zeinas.

Answer 9

wat would answer b?

Answer 10

1 : B & C
2 : C
3 : B&C

Answer 11

For 2, I'm not sure., the numbers are +14, and +3, which means the polynomial should be:
14 *3=42, and
14+3=17
x^2+17x+42
@RadEn what do you think?

Answer 12

And three is B and C.

Answer 13

-14 * -3 = 42
-14 + (-3) = -17

Answer 14

so 1 : B & C 2 C 3 is B?

Answer 15

3: B&C

Answer 16

@RadEn....The factors are (x-14)(x-3)
If the factors were -14 and -3, it would be
(x+14)(x+3)....It's a weird question

Answer 17

1 and 2 are correct, 3 still incomplete

Answer 18

3 cant be B & C it has to be one
