Equations and Their Zeros
- Let’s work with equations in standard and factored forms
4.1: Math Talk: Equations with Zero
Mentally find a value for \(a\) that will make the equation true.
\(4a = 0\)
\(3 \boldcdot 0 = 14a\)
\(0 \boldcdot a = 0\)
\(ab = 0\) with \(b \neq 0\)
4.2: Evaluating Quadratic Equations
- Evaluate each function for \(x = 6\).
- \(k(x)= 0.5x^2 - 3x\)
- What do these functions have in common?
- For each function, find another value of \(x\) that would give the same output as you found earlier.
4.3: Card Sort: Matching Equation Forms
Your teacher will give you a set of cards. Match each function in standard form with an equivalent function in factored form.
