The answer is -54
When you look at the first equation and the second one you can see that the variables arent in the same order. So you first have to change that.
-48a-42b-6c is now written the same way
Now you aha e to look for the rate of change
-48/8 =-6
-47/7=-6
-6/1=-6
All of them show that the rate of change was -6 so you just have to multiply the 9 by -6 to get your answer which is -54

Using factor theorem factorise each of the following

yuradex [85]

Answer:

(x + 1)(x - 1) (x- 2)(x - 5)

Step-by-step explanation:

<u>Solving in steps:</u>

x^4 - 7x^3 + 9x² + 7 x – 10=
(x^4 - 1 )- (7x^3 - 7x) + (9x^2 - 9) =
(x^2 + 1)(x^2 - 1) - 7x(x^2 - 1) + 9(x^2 - 1) =
(x^2-1)(x^2 + 1 - 7x + 9) =
(x + 1)(x - 1)(x^2 - 7x + 10) =
(x + 1)(x - 1)((x^2 - 2x) - (5x - 10)) =
(x + 1)(x - 1) (x- 2)(x - 5)
