Find the zeros of (x^2+4) (x-3)
Mila [183]

A multiplication is zero if and only if at least one of the factors is zero. So, in this case, the multipications equals zero when

x^2+4 = 0 \quad \lor \quad x-3=0

The first equation has no real solutions, because x^2 is a square, and thus it's positive. If you add 4 to a positive number, the result can't be zero.

The second equation has the solution

x-3=0 \iff x=3

So, globally, the expression equals zero if and only if x=3
