Capitolo 1, Problema R.6.49
Solve each quadratic equation using the zero-factor property. See Example 5. 4x² - 4x + 1 = 0
Guida verificata passo dopo passo1
Recognize that the given equation is a quadratic equation in the form $ax^2 + bx + c = 0$, where \(a = 4\), \(b = -4\), and \(c = 1\).
Check if the quadratic can be factored easily. Look for two numbers that multiply to \(a \times c = 4 \times 1 = 4\) and add to \(b = -4\).
If factoring is possible, express the quadratic as a product of two binomials: \((mx + n)(px + q) = 0\).
Apply the zero-factor property, which states that if \((mx + n)(px + q) = 0\), then either $mx + n = 0$ or $px + q = 0$.
Solve each linear equation separately to find the values of \(x\).

Introduction to Quadratic Equations
Zero-Factor Property
The zero-factor property states that if the product of two factors equals zero, then at least one of the factors must be zero. This property is used to solve quadratic equations by factoring them into binomials and setting each factor equal to zero to find the roots.
