WebLet's try the best Nature of roots rules. Solve Now. Nature of Roots depending upon Coefficients and Discriminant. The sum of the roots of a quadratic equation is equal to the negation of the coefficient of the second term, divided by the leading coefficient. The ... WebThe nature of the roots of quadratic equation is determine by the determinant, D. Where D= b 2 -4ac Now three cases are possible- If D>0 the roots are real and distinct. If D=0 the roots are real and equal. Id D<0 the roots are imaginary Value of roots are calculated by quadratic formula: quadratic equation formula Program/Source code

2.6 Nature of roots Equations and inequalities Siyavula

WebThe relationship between the discriminant value and the nature of roots are as follows: If discriminant > 0, then the roots are real and unequal If discriminant = 0, then the roots are real and equal If discriminant < 0, then the roots are not real (we get a complex solution) Discriminant Example WebBy the nature of roots we mean: whether the equation has real roots. if there are real roots, whether they are different or equal. The expression b2 – 4ac is called the discriminant of the quadratic equation because it discriminates among the four cases which can occur. If b2 – 4ac = 0, then the roots are real, rational, equal. long sleeve outdoor summer shirts
