Find the factored form of -12a+a^2=0

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

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 =
