Question

Find the zeros of the function.

Write the smaller solution first, and the larger solution second.
f(x) = (-x - 2)(-2x - 3)
smaller x =
larger x

Answer 1

The function is already factored, so it equals zero if and only if one of its factors equals zero:

`-x-2=0 \iff x-2`

or

`-2x - 3=0 \iff -2x=3\iff x=-(3)/(2)`

Since -2 is smaller than -3/2 the solutions are -2 and -3/2
