Question

4. Use Structure Explain why the sum x + X IS equal to 2x instead of x2.

Answer 1

Answer:

$x + x = (1 + 1)x = 2x \\ \\ x \times x = {x}^{1 + 1} = {x}^{2}$

Answer 2

Answer:

x+x is 2x because there coefficients are added and when two x's are multiplied their powers are added

Mathematical Explanation:

x+x=x(1+1)=x(2)=2x

Now

Multiplication:

x•x=x^(1+1)=x^2=x²
