Remember that the sum of tow cubes identity is:
So, to create our expression<span>, containing at least two variables, that can be factored using the sum of two cubes, we just need to replace </span>
and
with tow monomials with a different variable:
and
Lets replace those values in our identity:
Now that we have our expression, lets factor it using the sum of two cubes identity:
To verify if the factored form of our expression (right hand side) is equivalent to the original form (left hand side), we are going to expand the right hand side:
Since both sides of the equation are equal, we can conduce that the factored form of our expression is equivalent to the original expression.
Keep change flip so 5/8 * 3/2
Answer:
Step-by-step explanation:
Step-by-step explanation:
(12, -11) represents (x, y)
so 12 is x
-11 is y
now we need to do
x-9 and y+9
x-9=
12 - 9 = ???
y+9=
-11 + 9 = ???
then put into formate (x, y) as before
