What are the zeroes of f(x) = x2 + 5x + 6?

The zeroes are: -3 and -2

Step-by-step explanation:

f(x) = x² + 5x + 6

This is the in the format...

ax² + bx + c

To find the zeroes of a function, you must find what two numbers that add to B but multiply to C. In this case, you have to find two numbers that add to 5 but multiply to 6.

The two numbers are...

3 + 2 = 5 (This is correct because the two numbers add are equal to B)

3 x 2 = 6 (This is correct because the two numbers multiplied together are equal to C)

You then know that you have ( x + 3 ) and ( x + 2 )

Please do not get confused, the answers ARE NOT 3 and 2. You have to set the zeroes equal to 0.

Here's what I mean by that...

x + 3 = 0

Subtract 3 on both sides...

x = -3

The other zero...

x + 2 = 0

Subtract 2 on both sides...

x = -2

Your answers are x = -2 and x = -3, make sure you always set your answers to zero.

Hope this helps!

it is x equals 3   plese mark me really need it
