Respuesta :
If in the question it is 7x^2 and 3x^2, then
7x^2 - 4x + 10 + 3x^2 - 8
Re grouping the variables,
7x^2 + 3x^2 - 4x + 10 - 8
10x^2 - 4x + 2
The above would be the answer if the question was 7x^2 - 4x +10 +3x^2 - 8
7x^2 - 4x + 10 + 3x^2 - 8
Re grouping the variables,
7x^2 + 3x^2 - 4x + 10 - 8
10x^2 - 4x + 2
