which board geometrically represents 4x² - 1 using algebra tiles?
which board geometrically represents 4x² - 1 using algebra tiles?
Answer
Explanation:
Step1: Analyze the terms
The expression $4x^{2}-1$ has two - terms: $4x^{2}$ and $- 1$. We need 4 large square tiles to represent $4x^{2}$ (since each large square tile represents $x^{2}$) and 1 small square tile with a negative sign to represent $-1$.
Step2: Check the options
We look for a set of tiles that has 4 large square tiles labeled $+x^{2}$ and 1 small square tile labeled $-$.
Answer:
The second option (from the left) as it has 4 large square tiles labeled $+x^{2}$ and 1 small square tile labeled $-$.
