Question

What are the critical points obtained from \[12x(x-1)(x+2)=0\]?

Options

• \[x=0,\ x=-1,\ x=2\]

• \[x=0,\ x=1,\ x=-2\]

• \[x=1,\ x=-2\]

• \[x=0,\ x=2,\ x=-1\]

Answer 1

A product is zero when at least one factor is zero. The factors \[x\], \[x-1\], and \[x+2\] give \[0\], \[1\], and \[-2\], respectively.
