Change the variables to numbers: 3(-6)2+2(6)2
Multiply 3 and -6=-18*2= -36
Multiply 2 and 6=12*2=24
-36+24= -12

After you rewrite subtraction as addition of the additive inverse, how can the like terms be grouped? [3a2 + (-3a2)] + (-5ab + 8ab) + [b2 + (-2b2)] [3a2 + (-3a2)] + (-5ab + 8ab) + (b2 + 262) © (3a2 + 3a2)
