1. f(x) = -2x3 - 10x2 + 28x
Factor: x + 7
2. f(x) = 3x3 - 36x2 + 60x
Factor: 3x
3. f(x) = 4x3 - 16x2 - 240x
Factor: x - 10
4. f(x) = -3x3 + 54x2 - 240x
Factor: x - 10
5. f(x) = 2x3 - 28x2 + 48x
Factor: 2x
6. f(x) = -x3 + 49x
Factor: x - 7
7. f(x) = -4x3 + 60x2 - 224x
Factor: x - 7
8. f(x) = -x3 - 3x2 - 2x
Factor: x + 2
9. f(x) = -2x3 + 6x2 + 36x
Factor: x - 6
10. f(x) = -4x3 + 24x2 + 64x
Factor: x + 2
11. f(x) = 4x3 - 48x2 + 80x
Factor: 4x
12. f(x) = -2x3 + 4x2 + 96x
Factor: x - 8
13. f(x) = 3x3 + 6x2 - 9x
Factor: 3x
q 1 answer = x + 7 = o
x = -7
-2x3- 10x2 + 28 x
-2 x (-7)3 - 10 ( -7)2 + 28 X (- 7 )
686 - 490 -196
= 0
as like that all question are do
x = -7
-2x3- 10x2 + 28 x
-2 x (-7)3 - 10 ( -7)2 + 28 X (- 7 )
686 - 490 -196
= 0
as like that all question are do
