WebREAL AND UNEQUAL ROOTS When the discriminant is positive, the roots must be real. Also they must be unequal since equal roots occur only when the discriminant is zero. Rational Roots . If the discriminant is a perfect square, the roots are rational. For example, consider the equation. 3x 2 - x - 2 = 0. in which. a = 3, b = -1, and c = -2 WebNov 16, 2024 · y1(t) = er1t and y2(t) = er2t y 1 ( t) = e r 1 t and y 2 ( t) = e r 2 t. Now, if the two roots are real and distinct ( i.e. r1 ≠ r2 r 1 ≠ r 2) it will turn out that these two solutions are “nice enough” to form the general solution. y(t) =c1er1t+c2er2t y ( t) = c 1 e r 1 t + c 2 e r 2 t. As with the last section, we’ll ask that you ...
