14. If X and Y are integers, what is the value of XY?

(1) X^3 – 3X^2 – 2X – 8 = 0.

(2) 4 + 3Y = 2Y + 8

My aplogies folks, there are powers to x not coefficient.

Between C and E.
E, since we may get 3 dfferent values for x.

I think it is C. Can x be other than 4.

I would say C.

st.1
x can be only 4 (I tried some values, so I hope this is correct).
Alone not sufficient

st.2
y is 4
Alone not sufficient

Together we can find the value of xy.

Please correct me if I am wrong.


Regards,

Alex

Hi ALex,

I was wondering what values did you try? Is there any way to limit the trial numbers?

For the first one

x^3-3x^2-2x-8 = 0

(x-4)(x^2 +x+2) = 0

x = 4 or x^2+x+2 = 0 this quadratic equation has no solution since the discriminant is negative

so Our only solution is x = 4


That is why C is the right answer
