Answer» Step-by-step explanation: 1) infinite 2) k=4/3 3) alpha + beta = b/a 4) it MIGHT not be a parabolic function or it MAY be a polynomial with more than 2 roots with 2 roots real and other roots as imaginary. 5)let x n y be the roots. we know that x+y is -b/a x+y would be positive but if we take same sign numbers as a and b then we get the sum as negative. so the above mentioned question seems incorrect, though xy=c/a and xy would be positive n taking same sign for c and a would give a positive NUMBER . so this xy CONDITION satisfies according to the question but x+y doesn't. |
