Expanding and Simplifying (6a+5)(5a+3)
This article will guide you through the process of expanding and simplifying the expression (6a+5)(5a+3), ultimately presenting it in standard form.
Understanding the Problem
We are given a product of two binomials: (6a+5) and (5a+3). Our goal is to rewrite this product as a polynomial in standard form.
Expanding the Product
To expand the product, we can use the distributive property (also known as FOIL - First, Outer, Inner, Last).
- First: Multiply the first terms of each binomial: (6a)(5a) = 30a²
- Outer: Multiply the outer terms of the binomials: (6a)(3) = 18a
- Inner: Multiply the inner terms of the binomials: (5)(5a) = 25a
- Last: Multiply the last terms of each binomial: (5)(3) = 15
This gives us: 30a² + 18a + 25a + 15
Simplifying to Standard Form
Now we combine like terms:
30a² + (18a + 25a) + 15 30a² + 43a + 15
The Final Result
Therefore, the expression (6a+5)(5a+3) in standard form is 30a² + 43a + 15.
