The discriminant is the part of the quadratic formula under the radical, namely:



Two real and unequal roots. If is a perfect square, the roots are rational. Otherwise, they are irrational.
One real root with a multiplicity of two. That is to say that the trinomial is a perfect square and has two identical factors. The Fundamental Theorem of Algebra still holds because it allows counting roots up to the limits of their multiplicity.

A conjugate pair of complex roots of the form where is the imaginary number defined by

Terminology note: Rarely will you find a quadratic with purely imaginary roots. A quadratic that does not have real roots generally has complex number solutions which have a real part and an imaginary part. Hence, to say that a quadratic has "two different imaginary solutions" is almost always incorrect.

katrin [286]

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Use the mirror equation:

1/di + 1/do = 1/f

where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)

Substitute and solve for do.

1/do + 1/(-10 cm) = 1/(15 cm)

1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)

do = 6 cm

Hope it helps you

Regards,
