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 intersect … WebIf Δ > 0 Δ > 0, the roots are unequal and there are two further possibilities. Δ Δ is the square of a rational number: the roots are rational. Δ Δ is not the square of a rational number: the roots are irrational and can be expressed in decimal or surd form. Example Question Show that the roots of x2 − 2x − 7 = 0 x 2 − 2 x − 7 = 0 are irrational.
WebIf = b² -4 a c = 0, then roots are rational and equal. If = b² -4 a c > 0, and is a perfect square of a rational number, then roots are rational and unequal. If = b² -4 a c > 0 but is not a square of rational number, then roots are irrational and unequal. They form a pair of irrational conjugates p + q, p - q where p, q Q, q> 0.
