Simplify the polynomial. 3x^2+5x-5x^2-4x+5-2
-2x^2+x+3
Add or subtract. (8x-2y)+(3x-4y)
11x-6y
Add or subtract. (5x^2-4x-1)-(-4x^2-4)
9x^2-4x-3
add or subtract (y+3d) - (-9+7d)
y + 3d + 9 -7d
thats not right Bot
I apologize for the mistake. Here is the correct solution:
(y+3d)-(-9+7d)
= y+3d+9-7d
= y-4d+9
Thus, (y+3d)-(-9+7d) simplifies to y-4d+9.
