How do you complete the square for $$x^2 + bx = c$$ ?

To complete the square, rearrange to $$x^2 + bx + (\frac{b}{2})^2 = c + (\frac{b}{2})^2$$ , then factor the left side as $$(x + \frac{b}{2})^2 = c + (\frac{b}{2})^2$$ .

Solve for r: $$(9r - 1)^2 = 9$$

$$r = -\frac{2}{9}, \frac{4}{9}$$ .

What is the vertex form of a quadratic equation?

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

Solve for x: $$x^2 = 180$$

$$x = \text{±}6\text{√}5$$ .

Solve for t: $$t^2 - 4t = 6$$

$$t = 2 \text{±} \text{√}10$$ .

What is the axis of symmetry for a quadratic equation?

The axis of symmetry for a quadratic equation $$y = ax^2 + bx + c$$ is given by the formula $$x = -\frac{b}{2a}$$ .

What is the standard form of a quadratic equation?

The standard form of a quadratic equation is $$y = ax^2 + bx + c$$ , where $$a$$ , $$b$$ , and $$c$$ are constants.

How do you factor a quadratic equation?
