During Mr. Sanz’s tutorial class, four students were asked to write a number that is close to zero.

Find the roots of the equation below. x^2 - 6 + 9 = 0

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 =

Find the value of x. give reasons to justify your solutions! l, m ∈ kn
