The correct answer for this question is 11 - 13i.
This is how to answer this one:

(7 - 3i) (2 - i)
= [ (7*2) - (3i*2) - (7*i) + (3i*i) ]
Get the product of each term
= (14 -6i - 7i + 3i^2)

Group similar terms
= 14 - 13i - 3

Simplify.
= 11 - 13i

Side solution:
i = square root (-1)
i^2 = -1

Two fourth-degree polynomials are multiplied together. what is the degree of the product?

Snowcat [4.5K]

Answer:

The product of a fourth degree polynomial and a third degree polynomial is a 7th degree polynomial (just add the two degrees). Why is this the case? Remember, when you multiply variables with common bases, you add the exponents. Since the degree of a polynomial is just the largest exponent, you're really just adding the degrees when you multiply
