# Chapter 1 - Section 1.3 - Algebraic Expressions - 1.3 Exercises: 27

6$x^2$ + 7x - 5

#### Work Step by Step

The FOIL method stands for First, Outside, Inside, Last. This means you multiply the first term of each binomial together, in this instance 3x and 2x, giving 6$x^2$. Next you multiply the two "Outside" terms, meaning the first term of the first expression and the second term of the second expression, in this case 3x and -1, giving -3x. Next you multiply the "Inside" terms, meaning the second term of the first expression and the first term of the second expression, in this case 5 and 2x, giving 10x. Finally you multiply the last terms, 5 and -1, giving -5. Now add the terms from these four operations: 6$x^2$ + -3x + 10x + -5 6$x^2$ + 7s - 5
