What is the significance of the quadratic formula in solving quadratic equations?

The quadratic formula provides a systematic method to find the roots of any quadratic equation, regardless of whether the roots are real or complex.

Solve the quadratic equation $$-x^2 - 5x + 12 = 0$$ using the quadratic formula.

The solutions are $$x = 3$$ and $$x = -4$$ .

What happens to the solutions of a quadratic equation if the discriminant is positive?

There are two distinct real solutions.

What is the relationship between the coefficients of a quadratic equation and its roots?

For a quadratic equation $$ax^2 + bx + c = 0$$ , the sum of the roots is $$-\frac{b}{a}$$ and the product of the roots is $$\frac{c}{a}$$ .

What does it mean if a quadratic equation has complex solutions?

It means that the discriminant is negative, indicating that the roots cannot be represented as real numbers.

How can you verify the solutions obtained from the quadratic formula?

Substitute the solutions back into the original quadratic equation to check if they satisfy the equation.

What is the general form of a quadratic equation?

The general form of a quadratic equation is $$ax^2 + bx + c = 0$$ , where $$a$$ , $$b$$ , and $$c$$ are constants and @@a eq 0@@.

What is the vertex form of a quadratic equation?

The vertex form is $$y = a(x - h)^2 + k$$ , where (h, k) is the vertex of the parabola.
