Understanding the Equation t(t² - 5t + 6) = 0: A Complete Guide
Solving polynomial equations is a fundamental skill in algebra, and one particularly interesting expression is t(t² - 5t + 6) = 0. This equation combines linear and quadratic components, making it a great example for learning factoring, zero-product property, and quadratic solutions. In this article, we’ll explore how to solve this equation step-by-step, interpret its roots, and understand its applications.
What Does t(t² - 5t + 6) = 0 Mean?
The equation t(t² - 5t + 6) = 0 is a product of two factors set equal to zero. According to the Zero-Product Property, if the product of two factors equals zero, then at least one of the factors must be zero. So we set each factor equal to zero:
- First factor: t = 0
- Second factor: t² - 5t + 6 = 0
Solving these parts separately will give us all the solutions to the original equation.
Step 1: Solve the Linear Factor t = 0
This is straightforward: t = 0 is a solution by itself.
Step 2: Solve the Quadratic t² - 5t + 6 = 0
The quadratic equation t² - 5t + 6 = 0 can be solved by factoring, completing the square, or using the quadratic formula. Factoring works cleanly here.
Factoring
We look for two numbers that multiply to 6 and add up to -5. These numbers are -2 and -3. So, t² - 5t + 6 = (t - 2)(t - 3) = 0
Setting each factor to zero gives: t - 2 = 0 → t = 2 t - 3 = 0 → t = 3
Final Solutions
Combining both parts, the full set of solutions to t(t² - 5t + 6) = 0 is:
- t = 0
- t = 2
- t = 3
Thus, the roots are t = 0, 2, and 3. These three real and distinct solutions come from combining one linear and one quadratic factor.
