This is ur answer although remember to simplify
X^3 + 8 = x^3 + 2^3, a sum of two cubes.
So it can be factorised using the sum of two cubes rule...
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Therefore
x^3 + 8 = (x + 2)(x^2 - 2x + 4).
Hope this helps
This is a table with 6 lines.
In each line, the number in the first column is the 'x' value.
All you have to do on each line is ...
--- substitute the 'x' value in (100 + 23x), simplify it,
and write the result in the middle column
then
--- substitute the 'x' number in 90(1.2ˣ) , simplify it,
and write the result in the last column.
On the first line, x=0.
100 + 23x = 100 + 0 = 100. Write 100 in the middle column.
90(1.2ˣ) = 90(1) = 90. Write 90 in the last column.
Then go on to the second line, where x=1.
You'll make it.
