1. Divide: (x^2-10x+30) + (x-5) o x-10-6
o x-5- 5/x-5
o x-10- 30/x-5
o x-5+ 5/x-5

2. Divide: (x^3 -20x+16) + (x-4)
o -x^2+4x+4
o x^2+4x-4
o -x^2-4x+4
o x^2-4x+4

(didnt want to type 3 and 4 so theyre in the picture pls help)

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 =
