Solving the Quadratic Equation: v(v² – 5v + 6) = 0

When it comes to tackling quadratic equations, understanding how to factor expressions is an essential skill. One interesting equation you may encounter is:

v(v² – 5v + 6) = 0

Understanding the Context

This equation is not a standard quadratic in the form ax² + bx + c = 0 — instead, it's a product of two expressions set to zero. Let’s explore how to solve v(v² – 5v + 6) = 0 efficiently and understand its roots using factoring and algebraic methods.


What Does the Equation Mean?

The equation expresses that the product of v and a quadratic trinomial (v² – 5v + 6) equals zero. According to the Zero Product Property, if the product of two factors is zero, at least one of the factors must be zero. Therefore, we solve the equation by setting each factor equal to zero:

Step 2: Factor the Quadratic v² – 5v + 6

We now solve the quadratic v² – 5v + 6 = 0 through factoring.

We look for two numbers that:

  • Multiply to 6 (the constant term), and
  • Add up to –5 (the coefficient of the middle term).

These numbers are –2 and –3, because:
(–2) × (–3) = 6 and (–2) + (–3) = –5.

Thus, we factor the quadratic as:

v² – 5v + 6 = (v – 2)(v – 3)
