for instance, 7c^2 and c^2 are like terms and they add to
7c^2 + c^2 = 8c^2

you're not multiplying, you're just adding or subtracting

\[7c^2+c^2=(7+1)c^2=8c^2\] hope this helps, proceed this way, just add similar terms together

\[(7c^2 + 8c – 8) + (c^2 – 3c + 5)\]the parenthesis dont matter here since the sign outside is a plus sign:\[7c^2+8c-8+c^2-3c+5\]\[\color{blue}{7c^2}\color{red}{+8c}\color{green}{-8}\color{blue}{+c^2}\color{red}{-3c}\color{green}{+5}\] \[7c^2+c^2=8c^2\]\[8c-3c=5c\]\[-8+5=-3\] \[\color{purple}{8c^2+5c-3}\]
