Use the identity below to complete the tasks: a3 − b3 = (a − b)(a2 + ab + b2) When using the identity for the sum of two cubes t o factor 125q6 − r6s3. What is a? What is b?
2 answers:
Answer:
a=
b=
Step-by-step explanation:
Here is like the in the general formula.
So we can write as:
We can also write as:
Therefore:
a³=
b²=
Answer:
a = 5q²
b = r²s
Step-by-step explanation:
The given identity is
we have to use this identity to factor of two cubes given as [/tex]
As this expression is in the form of a³- b³
Here a is 5q² and b is r²s .
