Question

answer it please please...​

Answer 1

Answer:

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

       b² - 4ac = 0

       b² = 4ac

       ac = b²/4

       ac > 0
