find the domain of function

f(x)= (5x + 4)/(x^2 + 3x + 2)

x can't be -2 or -1?

• calculus -

how do you properly write the answer?

• calculus -

yes, x must not be equal to -2 and -1

(-00,-2)U(-2,-1)U(-1,+00)

*00==>infinity symbol (it should look like an 8 rotated 90 degrees clockwise..)
*U==>union
