Well, what I would do is line it up so you can cancel things out. I.e.:

(3x*2y-2)3

(9xy*3)3

Both of the 3s can cancel out

3x*2y-2

9xy*3

2y-2

3y*3

2y/3y-2/3=2/3-2/3=0

Plese read the complete procedure below:

Step-by-step explanation:

The polynomial is p(a) = (a^4 - 6a^3 + 3a^2 + 26a – 24)

1 -6 3 26 -24 | 1

1 -5 -2 24

1 -5 -2 24 0

The remainder is zero, then (a-1) is a factor of the polynomial

1 -6 3 26 -24 | 2

2 -8 10 72

1 -4 5 36 48

When p(a) is divided by (a-2) the remainder 28/p(a)

1 -6 3 26 -24 | - 4

-4 40 172 -792

1 -10 43 198 -816

When p(a) is divided by (a-2) the remainder -816/p(a)

c) I attached an image of the long division below:

Find the inverse of the following function f(x)= x+18

klasskru [66]

Answer:

f^-1(x) = x - 18

Step-by-step explanation:

y = x + 18

x = y + 18

x - 18 = y

f^-1(x) = x - 18

What is 2/4 + 4/5 - 7/10 ? Please help

Radda [10]

Make sure they have all common denominators
$\frac{2}{4} + \frac{4}{5} - \frac{7}{10}$

$\frac{2}{4} * \frac{5}{5} = \frac{10}{20}$

$\frac{4}{5} * \frac{4}{4} = \frac{16}{20}$

$\frac{7}{10} * \frac{2}{2} = \frac{14}{20}$

$\frac{10}{20} + \frac{16}{20} - \frac{14}{20}$

Add $\frac{10}{20} + \frac{16}{20} = \frac{26}{20}$
$\frac{26}{20} - \frac{14}{20} = \frac{12}{20}$

To simplify, you must find the largest common factor which 4
In $\frac{12}{20}$
12÷4=3 and 20÷4=5

The answer is $\frac{3}{5}$
