What is the product if a-3 and -2a^2+15a+6b2
Ierofanga [76]

The product if a-3 and -2a^2+15a+6b^2 is: -2a^3+21a^2+6ab^2-45a-18b^2

Step-by-step explanation:

In order to find the product of 2 expressions, distributive property can be used.

Given expressions are:

a-3\\and\\-2a^2+15a+6b^2

Product of given expressions

= (a-3)(-2a^2+15a+6b^2)\\= a(-2a^2+15a+6b^2)-3(-2a^2+15a+6b^2)\\= -2a^3+15a^2+6ab^2+6a^2-45a-18b^2

Combining like terms

= -2a^3+15a^2+6a^2+6ab^2-45a-18b^2\\=-2a^3+21a^2+6ab^2-45a-18b^2

Hence,

The product if a-3 and -2a^2+15a+6b^2 is: -2a^3+21a^2+6ab^2-45a-18b^2

Keywords: Expressions, product

If you turn the years into months(60) and multiply it by the 180 per month =, you end with 10,800 then multiply that by .49 because its a percent and get a total of 5,292. Finally add the 10,800 and 5,292 and the answer is $16,092.
