Answer:
Triangle A
Step-by-step explanation:
Answer : option B
We have -2 in the given option
Lets use synthetic division and divide by -2
First write the coefficient of all the terms in f(x)
-2 3 10 4 -8
0 -6 -8 8
------------------------------------------------------
3 4 -4 0
We got remainder =0 , so -2 is one of the zero
Resultant expression is 3x^2 + 4x -4
Lets use synthetic division and divide by -2 again
-2 3 4 -4
0 -6 4
------------------------------------------------------
3 -2 0
We got remainder =0 , so -2 is again a zero
Resultant expression is 3x - 2
we set 3x -2 =0
Add 2 on both sides
3x = 2
Divide by 3 on both sides
So zeros are
Answer:
3n+2(n+2)=9n+12
3n+ 2n + 4 = 9n + 12
3n+ 2n +4 - 4 = 9n + 12 - 4
3n + 2n - 9n = 12 - 4
5n - 9n = 8
<u>-4n </u> = <u>8</u>
-4. -4
n. = - 2
