Answer:
To expand "(x-3)(x + 5)", you can follow these steps:
1. Multiply the first term of the first binomial (x) by each term in the second binomial:
x * x = x^2
x * 5 = 5x
2. Multiply the second term of the first binomial (-3) by each term in the second binomial:
-3 * x = -3x
-3 * 5 = -15
3. Combine the results from step 1 and step 2 to get the expanded expression:
x^2 + 5x - 3x - 15
4. Combine like terms:
x^2 + 2x - 15
Therefore, the expanded form of "(x-3)(x + 5)" is x^2 + 2x - 15.
