Question

If one of the zeroes of the cubic polynomial r8 - 7x + 6 is 2, then the product of the
other two zeroes is :
(a) 2
(b)-2
(c) 3
(d) -3.​

Answer 1

Answer:

c) 3..….......................

Answer 2

Answer:

Step-by-step explanation:

Because -2 is a zero, you can factor out (x-(-2)).

Use long division:

x^3+2x^2–2x^2–4x−3x−6  

=(x+2)(x^2–2x−3)  

And then it's easy to factor a quadratic:

=(x+2)(x+1)(x−3)
