2. EOCT Practice C a)2a (a + 3) ( a + 5) b)2a (a – 3) (a + 5) c)2a (a + 3) (a – 5) d)2a ( a – 3) (a – 5) Which expression is equivalent to 2a 3 – 4a 2 – 30a?

3. Add and Subtract Radicals 1.You can only add or subtract radicals that have the EXACT SAME radicand. 2.Then add/subtract ONLY the number OUTSIDE the radical 3.Then, check to see if you can simplify!! 1.You can only add or subtract radicals that have the EXACT SAME radicand. 2.Then add/subtract ONLY the number OUTSIDE the radical 3.Then, check to see if you can simplify!!
