Step-by-step explanation:

Step 1: Define

P(x) = x² + 2x - 7

P(-3) is x = -3

Step 2: Evaluate

  1. Substitute:                    P(-3) = (-3)² + 2(-3) - 7
  2. Exponents:                   P(-3) = 9 + 2(-3) - 7
  3. Multiply:                        P(-3) = 9 - 6 - 7
  4. Subtract:                       P(-3) = 3 - 7
  5. Subtract:                       P(-3) = -4
