Question

it being given that 2 is one of the zeroes of the polynomial x3-4x2+x+6 find its other zero​

Answer 1

Answer:

3, -1

Step-by-step explanation:

x³-4x²+x+6

=x³ -2x² -2x² +4x -3x +6

=x²(x-2)-2x(x-2)-3(x-2)

=(x-2)(x² -2x -3)

=(x-2)(x² -3x +x -3)

=(x-2){x(x -3) +1(x -3)}

=(x-2)(x-3)(x+1)

other zeros are 3 and -1
