Write the sentence as an equation. b increased by 281 is d

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
