Write Problem: Write down the problem.Add the two polynomials (7z2+6z) and (3z+2).
Combine Polynomials: Remove any parentheses and combine like terms.Since there are no subtraction signs or negative coefficients outside the parentheses, we can simply drop the parentheses and combine like terms.(7z2+6z)+(3z+2)=7z2+6z+3z+2
Remove Parentheses: Combine the like terms.The like terms are the terms that have the same variable raised to the same power. In this case, 6z and 3z are like terms.7z2+(6z+3z)+2=7z2+9z+2
Combine Like Terms: Write the final simplified expression.The final simplified expression is 7z2+9z+2.
