Find the zeros of the polynomial given one factor. Use synthetic division. f(x) = x³-12x²+47x-60; x-3

• x= 3, 4,5

• x= -3, -4, -5

• x= -3, 4,5

• x= 3,-4,-5

• f(x) = (x + 5) (x - 2) (3x + 7)

• f(x) = (x - 5) (x + 2) (3x + 7)

• f(x) = (x + 5) (x - 2) (3x - 7)

• f(x) = (x - 5) (x + 2) (3x - 7)
