Third zero will be '1' f(x)= 2x^3+3x^2-5x-6 Zeros are a,b and c. ab =3 (given) Product of zeros= - constant term/coeff. of x^3 = -(-6/2)=1 So c= 3/3=1

Learn Science from the Scientist

I don’t think the question is correct. The product of three roots = - Const/ coefficient of cubic term which yields -(-6)/2=3. Since product of two roots is 3 then the third one has to be 1. But 1 can’t be the root of equation. As one can easily subtitle x=1 in the equation and see it doesn’t...

I don’t think the question is correct. The product of three roots = - Const/ coefficient of cubic term which yields -(-6)/2=3. 

Since product of two roots is 3 then the third one has to be 1. But 1 can’t be the root of equation. As one can easily subtitle x=1 in the equation and see it doesn’t yield 0. 

However, the question will be correct if one says that the product of two root is -3. Then answers would be -1, -2 and 3/2.

If x:y = 9:10, find the value of (5x + 3y) : (5x - 3y)?
The answer is 5:1. SOL :- x : y=9 : 10==> 10 x=9 y==> 5 x = 9 y/2, substituting 9y/2 for 5x in ( 5 x + 3 y) : (5 x - 3 y) gives 5: 1
