What Is The Product Of The Polynomials 4-A And A^2+7a-18
What is the product of the polynomials 4-a and a^2+7a-18
Answer:
- a³ - 3a² +46a -72,
Step-by-step explanation:
This is an example of multiplication of binomial by another polynomial.
(4-a) ( a^2+7a-18)
= 4(a²) + 4(7a) - 4(18) - a(a²) - a(7a) - a(-18)
= 4a² + 28a - 72 - a³ -7a² + 18a (combine like terms)
= - a³ - 3a² +46a -72
