Find the product of (-4x - 3)^2. Use algebra tiles if needed. Write the product in standard form.

1 answer

To find the product of \((-4x - 3)^2\), we can use the formula for squaring a binomial, which is \((a + b)^2 = a^2 + 2ab + b^2\).

Let: \[ a = -4x \quad \text{and} \quad b = -3 \]

Now, we apply the formula:

  1. Calculate \(a^2\): \[ (-4x)^2 = 16x^2 \]

  2. Calculate \(2ab\): \[ 2 \cdot (-4x) \cdot (-3) = 2 \cdot 12x = 24x \]

  3. Calculate \(b^2\): \[ (-3)^2 = 9 \]

Now, putting it all together, we have: \[ (-4x - 3)^2 = a^2 + 2ab + b^2 = 16x^2 + 24x + 9 \]

Thus, the product of \((-4x - 3)^2\) in standard form is: \[ \boxed{16x^2 + 24x + 9} \]
