When you divide 2x² by x², you are essentially dividing the coefficients (2 ÷ 1) and subtracting the exponents (2 - 2) of the variables. This simplifies to 2x^(2-2), which equals 2x^0. Any non-zero number raised to the power of zero is 1, so the final answer is 2.

It is: -2x squared
2x2 + 2x = 2x(x+1)
x^2+2x^2=3x^2
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
