Question

resolve this equation

Answer 1

The expression above can be resolved to become; (5a + b)³

According to the question:

• We are required to determine resolve the expression as given in the question.

To resolve the expression given;

• We are required to multiply the polynomials as follows;

• (5a + b) (25a² + 10ab² + b²)

• = 125a³ + 50a²b² + 5ab² + 25a²b + 10ab³ + b³

However; the expression above can be factorised to become;

• (5a + b)³

Upon expansion; (5a + b)³ yields the expression gotten earlier;

• 125a³ + 50a²b² + 5ab² + 25a²b + 10ab³ + b³
