What is the factored form of the expression $$49x^2 - 4$$ ?

The factored form is $$(7x + 2)(7x - 2)$$ .

How do you identify the vertex and axis of symmetry of the function $$y = -2(x + 3)^2 + 4$$ ?

The vertex is $$(-3, 4)$$ and the axis of symmetry is $$x = -3$$ .

Simplify the expression $$(6 - 3i)(5 + 4i)$$ .

The simplified expression is $$42 + 9i$$ .

What is the product of the expressions $$(4x - 5)(2x - 4)$$ ?

The product is $$8x^2 - 26x + 20$$ .

What is the formula for the vertex of a quadratic function in standard form $$y = ax^2 + bx + c$$ ?

The vertex can be found using the formula $$x = -\frac{b}{2a}$$ .

What is the probability formula for independent events?

The probability of independent events A and B occurring is $$P(A) \times P(B)$$ .

What is the difference between a cube and a sphere in geometry?

A cube is a three-dimensional shape with six equal square faces, while a sphere is a perfectly round three-dimensional shape with no edges or vertices.

What is the distributive property in algebra?

The distributive property states that $$a(b + c) = ab + ac$$ .

How do you find the axis of symmetry for a quadratic function?

The axis of symmetry can be found using the formula $$x = -\frac{b}{2a}$$ .

What is the standard form of a quadratic equation?

The standard form is $$y = ax^2 + bx + c$$ .

What does it mean to simplify an expression?

Simplifying an expression means to reduce it to its simplest form by combining like terms and performing operations.

What is the significance of the vertex in a quadratic function?

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.

What is the formula for the probability of an event?

The probability of an event is given by $$P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$ .
