Question

Find the difference of the roots of the quadratic equation. ​

Answer 1

Answer:

Difference in roots signify the 1/2 cycle of the of the system time base. ... If the roots are a and b, then (a + b) = -p and (ab) = q; therefore (a - b)^2 = (a + b)^2 - 4(ab) = (p^2) - 4q; this leads to the formula |a - b| = root{ (p^2) - 4(q).

Answer 2

Difference in roots signify the 1/2 cycle of the of the system time base. ... If the roots are a and b, then (a + b) = -p and (ab) = q; therefore (a - b)^2 = (a + b)^2 - 4(ab) = (p^2) - 4q; this leads to the formula |a - b| = root{ (p^2) - 4(q).
