Front

Define a quadratic equation.

Back

A quadratic equation is a polynomial equation of the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

Front

What is the quadratic formula used to find the roots of a quadratic equation?

Back

x = (-b ± √(b² - 4ac)) / (2a)

Front

What does the discriminant of a quadratic equation tell us?

Back

The discriminant (b² - 4ac) indicates the nature of the roots: if > 0, two distinct real roots; if = 0, one real root; if < 0, two complex roots.

Front

What is the standard form of a complex number?

Back

A complex number is expressed in the form a + bi, where a is the real part and b is the imaginary part.

Front

How do you add two complex numbers?

Back

To add complex numbers, combine the real parts and the imaginary parts separately.
