To add or subtract polynomials, we need to combine like terms.
(2x(2)+6x+1)+(-7x(2)+2x-3)
First, we can simplify the expression by removing the parentheses around the second polynomial and changing the sign of each term inside the parentheses:
2x(2) + 6x + 1 - 7x(2) - 2x + 3
Now, we can combine the like terms by grouping the terms with the same variable and exponent:
(2x(2) - 7x(2)) + (6x - 2x) + (1 + 3)
Simplifying further:
-5x(2) + 4x + 4
Therefore, the simplified result of (2x(2)+6x+1)+(-7x(2)+2x-3) is -5x(2) + 4x + 4.
