Use the quadratic formula x = In general quadratic equation has two solutions, which may be real or complex numbers. If b2 - 4ac, then two roots are equal and real numbers. If b2 〉 4ac, that is b2-4ac is positive, then two roots are unequal and real numbers. If b2く4ac, that is b2-4ac is negative, then two roots are unequal complex numbers and cannot represent physical quantities and quadratic equation has mathematical solution but no physical solution Conclusion: 4.9t2 + 2t -20- 0 is a quadratic equation Here, b- > 4ac, then two roots are unequal and real numbers.
