What is the first step in solving $$\frac{(x-1)^2}{2} = 32$$ using the square root property?

Multiply both sides by 2 to eliminate the fraction: $$(x-1)^2 = 64$$ .

Solve $$-7x^2 + 21 = 84$$ for x.

First, simplify to get $$-7x^2 = 63$$ , then $$x^2 = -9$$ , which has no real solutions.

How do you apply the square root property to $$x^2 = a$$ ?

Take the square root of both sides, giving $$x = ±\text{sqrt}(a)$$ .

What is the solution to $$\frac{(x+4)^2 - 7}{-6} = 0$$ ?

First, isolate the squared term to find $$x = -5$$ and $$x = -3$$ .

What is the significance of the discriminant in quadratic equations?

The discriminant, given by $$b^2 - 4ac$$ , determines the nature of the roots: if positive, two real solutions; if zero, one real solution; if negative, no real solutions.

How do you check your solutions for quadratic equations?

Substitute the solutions back into the original equation to verify that both sides are equal.

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.

What is the axis of symmetry in a quadratic equation?

The axis of symmetry is the vertical line that divides the parabola into two mirror images, given by $$x = -\frac{b}{2a}$$ .

What is the standard form of a quadratic equation?

The standard form is $$ax^2 + bx + c = 0$$ , where a, b, and c are constants.

How do you factor a quadratic equation?

To factor, find two numbers that multiply to $$ac$$ and add to $$b$$ , then rewrite the equation in factored form.
