Answer:

x^{3} +2^{3}=(x+2)(x^{2} -2x+2^{2} )

Step-by-step explanation:

The general expansion of a polynomial of type a^{3} +b^{3} is given as follows:

a^{3} +b^{3} =(a+b)(a^{2} -ab+b^{2} )

Given polynomial is x^{3} +8

This can be written as x^{3} +2^{3}, which is of the form  a^{3} +b^{3}.

So we can use the general form to expand this polynomial where;

a→x

b→2

x^{3} +2^{3}=(x+2)(x^{2} -x\times2+2^{2} )

x^{3} +2^{3}=(x+2)(x^{2} -2x+2^{2} )

Solve the following equation
Gnoma [55]
40x+8x^2=0 can be solved for x (there are two solutions):

Divide all 3 terms by the greatest common multiple (which is 8x):

40x+8x^2=0
------------- -----
       8x       8x

5 + x = 0             produces the root x = - 5.   

Setting 8x = 0 and solving for x produces the root x = 0.

Be certain to check these results.  substitute x = -5 into 40x+8x^2=0.  Is the resulting equation true or false?  Next, subs. x=-5 into 40x+8x^2=0.  Is the resulting equation true or false?

In arithmetic sequence the first term is 5 and the common difference is 4. Determine the 6th term of sequence
Harlamova29_29 [7]

Answer:

The 6th term of the sequence is 25

Step-by-step explanation:

first term = a = 5

common difference = d = 4

The nth term of a sequence is

T_n = a + (n - 1)d

Therefore, the 6th term of the sequence is

T_6 = a + (6 - 1)d

T_6 = a + 5d

T_6 = 5 + 5(4)

T_6 = 5 + 20

T_6 = 25
