Sum of zeroes of the polynomial x2−25 is
5
-5
0
25
Here, we will get x as +5 and -5, so the sum will be 0.
If α, β are zeroes of the polynomial f(x) = 2x2 + 5x - 10, then value of αβ is
The factors of x4 + x2 + 25 are (a) (x2 + 3x + 5) (x2 − 3x + 5) (b) (x2 + 3x + 5) (x2 + 3x − 5) (c) (x2 + x +5) (x2 − x + 5) (d) none of these
