Answer:
A quadratic equation with 1 solution has 1 zero, meaning it touches the x axis once. For example, x² - 6× + 8 has 2 solutions,as the discriminant is 4
A quadratic equation with no solution has no zeros meaning it does not touch the x axis. Therefore the discriminant must be less than 0. For example, 2x² - 3× +4 has no solution, as the discriminant is -23.
(for ax² + bx +c the discriminant is b²- 4ac)
