Given the equations V2x= V1x+ax$$\Delta$$t and $$\Delta$$X= V1x$$\Delta$$t+ 1/2ax$$\Delta$$t2, i need to derive the equation V2x2=V1x2+2ax$$\Delta$$t. please help me!

Welcome to PF.

What variable do you need to eliminate from the equations you are given to get the answer? (Btw, your statement of the final equation is in error.)

Armed with that ... it's Nike time ... just do it.
