If the zeros of quadratic polynomial ax² + bx + c.c is not equal to zero are equal then c and a will have the same sign.

The zeroes of the given quadratic polynomial ax2 + bx + c, c ≠ 0 are equal. If coefficient of x² and the constant term have same sign which is c and a have the same sign. While b which is the coefficient of x can be positive/negative but not zero.

Example – x² – 4x +4 = 0

(x +2)² = 0

x = -2

Given the quadratic polynomial ax² + bx + c, c ≠ 0 are equal, which means D = 0

Given the quadratic polynomial ax² + bx + c, c ≠ 0 are equal, which means D = 0

b² – 4ac = 0

b² = 4ac

ac = b²/4

ac > 0

Answer:Discreminent =0

B^2 – 4AC=0

B^2 =4AC
