# Math Help - Determinant of matrix

1. ## Determinant of matrix

Find the determinant of the matrix

x , y , z
1 , 1 , 1
y+z, x+z , x+y

should i get a real number?

2. should i get a real number?

Not when there are variables as entries--just work it like any 3x3 det

3. I spoke too soon after actually working this determinant I get 0.

In general you would have variables in the answer

4. Got it!! Thanks Calculus26 =)
