Question

roots of the quadratic equation are equal then b²-4ac​

Answer 1

Step-by-step explanation:

Thus, the roots of the equation ax2 + bx + c = 0 are real and equal if b2 – 4ac = 0. ... If b2 - 4ac > 0 then √b2−4ac will be real and non-zero. As a result, the roots of the equation ax2 + bx + c = 0 will be real and unequal (distinct) if b2 - 4ac > 0.
