[tex]2a-8a^2+a-3a^2\text{ + 5 - 2 = }3a-11a^2\text{ + 3}[/tex]
To simplify by combining like terms, we bring the terms with the same alphabets description together.
In this case, the ones with a come together, the ones with a^2 also come together.
Thus, we have;
[tex]\begin{gathered} 2a-8a^2+a-3a^2\text{ + 5 - 2} \\ \\ a-\text{terms ; 2a + a} \\ \\ a^2terms;-8a^2-3a^2 \\ \\ \text{And; +5 -2} \\ \\ We\text{ have;} \\ \\ 3a-11a^2\text{ + 3} \end{gathered}[/tex]
