What we are going to do with this problem is combine all the like terms.  so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a. thus: 8[latex] a^{2} [/latex]+(-3[latex] a^{2} [/latex] is going to equal 5[latex] a^{2} [/latex] because adding a negative is just like subtracting. then we move on to (6a)-(2a) giving us 4a 5 is the only term that stays the same because there are no other similar terms. last but not least, put the equation together! answer: 5[latex] a^{2} [/latex]+4a+5
