Question

What polynomial identify should be used to prove that 35=8+27

Answer 1

Explanation:

Answer:

Sum of cubes identity should be used to prove 35 =3+27

Explanation:

Prove that : 35 = 8 +27

Polynomial identities are just equations that are true, but identities are particularly useful for showing the relationship between two apparently unrelated expressions.

Sum of the cubes identity:

Take RHS

8+ 27

We can write 8 as and 27 as .

then;

8+27 =

Now, use the sum of cubes identity;

here a =2 and b = 3

or

= LHS proved!

therefore, the Sum of cubes polynomial identity should be used to prove that 35 = 8 +27
