Find the Sum & Product of Roots of Quadratic Functions

Unlock the Relationship Between Roots and Coefficients! 🔢 In this tutorial, we explore the Sum and Product of the Roots of quadratic equations. We define the standard form ax^2 + bx + c = 0 and introduce the formulas that link the roots directly to the coefficients: the sum is -b/a and the product is c/a.

What you will learn in this video:
• Core formulas for finding the sum (-b/a) and product (c/a) of roots.
• Comparing manual factoring vs. using the sum and product shortcut.
• Solving examples with integer, fractional, and negative coefficients.
• Writing a quadratic equation when given its two roots.
