Expanding and Simplifying (x-3)(x+8)

This expression represents the multiplication of two binomials: (x-3) and (x+8). To simplify this, we can use the FOIL method.

FOIL stands for:

  • First: Multiply the first terms of each binomial.
  • Outer: Multiply the outer terms of the binomials.
  • Inner: Multiply the inner terms of the binomials.
  • Last: Multiply the last terms of each binomial.

Let's apply this to our expression:

F: x * x = O: x * 8 = 8x I: -3 * x = -3x L: -3 * 8 = -24

Now, we add all the terms together:

x² + 8x - 3x - 24

Finally, combine the like terms:

x² + 5x - 24

Therefore, the expanded and simplified form of (x-3)(x+8) is x² + 5x - 24.
