Question

Find the zeros of the function. f(x) = x^2 + 3x + 2

Answer 1

This function returns a zero value when x is equal to negative one or negative two.

Explanation:

We can solve this by factoring the function:

f(x) = x² + 3x + 2

= x(x + 1) + 2(x + 1)

= (x + 1)(x + 2)

So function equals zero when x = -1 or -2
