The Total solution for NCERT class 6-12
The zeroes of the quadratic polynomial x2 + ax + a, a ≠ 0,(a) cannot both be positive(b) cannot both be negative(c) area always unequal(d) are always equal
(a) Let p(x) = x2 + ax + a, a ≠ 0On comparing p(x) with ax2 + bx + c, we geta = 1, b = a and c = a
So,both zeroes are negative.Hence, in any case zeroes of the given quadratic polynomial cannot both thepositive.
