Expanding and Simplifying (x-4)(2x+3)

This article will walk through the process of expanding and simplifying the expression (x-4)(2x+3).

Understanding the Expression

The expression (x-4)(2x+3) represents the product of two binomials:

  • (x-4) is a binomial with terms "x" and "-4"
  • (2x+3) is a binomial with terms "2x" and "3"

Using the FOIL Method

The FOIL method is a common technique for expanding binomials. It stands for:

  • First: Multiply the first terms of each binomial (x * 2x)
  • Outer: Multiply the outer terms of the binomials (x * 3)
  • Inner: Multiply the inner terms of the binomials (-4 * 2x)
  • Last: Multiply the last terms of each binomial (-4 * 3)

Let's apply FOIL to our expression:

  • First: x * 2x = 2x²
  • Outer: x * 3 = 3x
  • Inner: -4 * 2x = -8x
  • Last: -4 * 3 = -12

Combining Like Terms

After applying FOIL, we get the following expression:

2x² + 3x - 8x - 12

Now, combine the like terms (3x and -8x):

2x² - 5x - 12

The Simplified Expression

Therefore, the expanded and simplified form of (x-4)(2x+3) is 2x² - 5x - 12.
