the point P = (x, 1/2) lies on the unit curcle shown below. what is the value of x in the simplest 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 =

Yo need asap pls ! markin da brainiest too !

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30
