multiply (w-3)(w+5)
To multiply (w-3)(w+5), you can use the factoring method.
First, multiply the terms in the parentheses:
(w-3)(w+5) = w*w + w*5 - 3*w - 3*5
Next, simplify:
w*w + w*5 - 3*w - 3*5 = w^2 + 5w - 3w - 15
Combine like terms:
w^2 + 5w - 3w - 15 = w^2 + 2w - 15
So, the expression (w-3)(w+5) simplifies to w^2 + 2w - 15.
