2/9/2018 · The zeroes of the quadratic polynomial x2 + 99x + 127 are (a) Both positive … positive and one negative (d) Both equal, both negative. x2 +99x+127. Here product of roots = 127. And sum of roots = ?99. Here product of roots is positive ? both roots are positive or both roots are negative. But sum of roots is negative ? both roots are negative are only choice as roots can be both positive or both negative as per above statement. ? both roots are negative.
