Expanding the Expression: (d+6)(2d^2-d+7)
This expression represents the product of two polynomials: a binomial (d+6) and a trinomial (2d^2-d+7). To simplify this expression, we will use the distributive property, commonly known as FOIL (First, Outer, Inner, Last).
Using FOIL to Expand
1. First: Multiply the first terms of each polynomial:
- d * 2d^2 = 2d^3
2. Outer: Multiply the outer terms of each polynomial:
- d * 7 = 7d
3. Inner: Multiply the inner terms of each polynomial:
- 6 * 2d^2 = 12d^2
4. Last: Multiply the last terms of each polynomial:
- 6 * -d = -6d
- 6 * 7 = 42
Combining the Terms
Now, we combine all the terms we obtained:
2d^3 + 7d + 12d^2 - 6d + 42
Finally, we arrange the terms in descending order of their exponents:
2d^3 + 12d^2 + d + 42
