Question

Multiply the polynomials (5a^2+2-7) and (3a^2-a+1). Simplify the answer

Answer 1

Explanation:

(5a^2+2-7)

5a^2-5

(3a^2-a+1)

3a^-a+1

Answer 2

Answer: The answer is 15a^4+a^3-18a^6-5a-7

Explanation:

Step 1: (5a^2+2a-7) (3a^2-a+1)

Step 2: 5a^2(3a^2-a+1) +2a(3a^2-a+1)-7(3a^2-a+1) multiply

Step 3: 15a^4-5a^3+5a^2+6a^3-2a^2+2a-21a^2+7a-7 (Combine like terms

Step: 4 15a^4+a^3-18a^6-5a-7

So first we write the equation then we take the the first polynomial equation and multiply it by the second. After that we multiplied everything combine like terms and simplify to the lowest terms possible!

Hope this helps! :D
