WebIf \(Δ = 0\), the roots are equal and we can say that there is only one root. If \(Δ > 0\), the roots are unequal and there are two further possibilities. \(Δ\) is the square of a rational … WebThe roots can be easily determined from the equation 1 by putting D=0. The roots are: x = − b 2 a o r − b 2 a D < 0: When D is negative, the equation will have no real roots. This means the graph of the equation will not …
