What are the zeroes of f(x) = x^2 + 5^x + 6? a. x = −2, −3 b. x = 2, 3 c. x = −2, 3 d. x = 2, −3

You can factor it by using a method of your choice. I'll just use guess and check, because it's the easiest in this situation (for me). I need two numbers that multiply to 6, and add up to 5. Those two number are 2 and 3. 2 * 3 = 6, and 2 + 3 = 5. So, I can write the above equation as follows in factored form:


Then it's pretty easy to recognize the zeros because I just have to solve for each parentheses by doing this:


and



So, your zeros are at -2 and -3. Your answer is A. If any step doesn't make sense, hmu!
