Simplifying the Expression (3y-4)(2y+7)+11y-9
This article will guide you through the process of simplifying the expression (3y-4)(2y+7)+11y-9.
Understanding the Expression
The expression consists of two main parts:
- (3y-4)(2y+7): This is a product of two binomials.
- 11y-9: This is a simple binomial.
Expanding the Product
To simplify the expression, we first need to expand the product of the binomials. We can do this using the FOIL method:
- First: Multiply the first terms of each binomial: (3y)(2y) = 6y²
- Outer: Multiply the outer terms of the binomials: (3y)(7) = 21y
- Inner: Multiply the inner terms of the binomials: (-4)(2y) = -8y
- Last: Multiply the last terms of the binomials: (-4)(7) = -28
Combining the results, we get: (3y-4)(2y+7) = 6y² + 21y - 8y - 28
Combining Like Terms
Now, we can combine the like terms in the entire expression:
6y² + 21y - 8y - 28 + 11y - 9
This simplifies to: 6y² + 34y - 37
Final Result
The simplified form of the expression (3y-4)(2y+7)+11y-9 is 6y² + 34y - 37.
