Answer» Answer: >> In QUADRATIC equation : A * x^2 + Bx + C = 0 >> B is always the negative sum of roots and whereas product of the roots is EQUAL to A*C. >> So, in this question VALUE of "b is 2". >> And, Value of "a is 1" ************** ~ i hope i was able to help you. ~~ Have a great day AHEAD! |
