Solutions of (x+4)^2-3(x+4)-3

Ihonestly don’t understand this at all

Can some one me, i’ve been asking for so long

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 =
