The Total solution for NCERT class 6-12
If the zeroes of the quadratic polynomial ax2 + bx + c, c ≠ 0 are equal, then(a) c and a have opposite signs(b) c and b have opposite signs(c) c and a have the same sign(d) c and b have the same sign
(c) The zeroes of the given quadratic polynomialax2 + bx + c, c ≠ 0 are equal. If coefficient of x2 and constant term have the same signi.e., c and a have the same sign. While b i.e.,coefficient of x can be positive/negative but not zero.
