Answer: x² + 2x - 15

Step-by-step explanation:

<u>Concept:</u>

When we encounter questions that ask us to simplify expressions that consist of multiple parentheses, it is suggested to use the FOIL method to ease the process.

  • First
  • Outer
  • Inner
  • Last

<u>Solve:</u>

Given

(x - 3) (x + 5)

Expand parentheses

x² + 5x - 3x - 15

Combine like terms

x² + (5x - 3x) - 15

x² + 2x - 15

Hope this helps!! :)
