1. unite similar terms with parenthesis. x=2 y=3 and z=5 find the value of
ax to the 2nd powercy+ax2ax to the 2nd power+ 2cy to the 2nd poweraxcy to the 2nd power+ ax to the 2nd power+ cy

ax^2  cy + ax  2ax^2 +2cy^2 ax cy^2 + ax^2 +cy = cy^2
The ax, ax^2 and cy terms cancel each other out, leaving you with cy^2 (c * y squared or c * y to the second power).
cy^2 = c * 3 * 3 = 9c (A negative times a negative is a positive).
I hope this helps. Thanks for asking.
