Simplifying Single Like Terms

Simplifying Single Like Terms


Now we’re going to start question one now, so you all know what like terms are, you just need to answer this question for me. It says simplify 8d plus 2d plus 3d. So first of all guys are they like terms?

Are those three terms like terms? Of course, they are because they all have d, d is the same so that’s why all three of them are like terms, so we can add them together or subtract them together but in this case, we’re going to add them. So when we add these you keep that like term as it is okay and you only work with the coefficients.

What do I mean by coefficients guys? Coefficients are the number in front of the pronumeral so the coefficient of 3d is 3, the coefficient here is 2 and the coefficient here is 8, so we add up those coefficients, like this. So we add eight plus two plus three and then stick the d at the end. And then what’s eight plus two plus three? Thirteen!!! So the answer is thirteen d, so still ends in d okay, the like term itself then the pronumeral that’s the same should not change it should still remain as d okay? But you only work with the coefficients, just remember that that’s the key thing okay? So let’s go to the next one.

Question two? Okay, simplify e plus five e. Are they like terms? Yes, they are, they both end in e and e only. So remember guys, e it’s if there’s nothing in front of v what’s the coefficient of e here. Can someone tell me? It’s going to be one isn’t it, if there’s nothing in front of the pronumeral it. Simply means one so again let’s add up the print sorry the coefficients like this, so it’s one plus five and then we stick the e at the end, so one plus five is six so the answer is six e. Again leave that pronumeral as it is just working with the coefficients okay? So it’s very simple.

Question three. Okay again 12a minus 2a minus 7a, these are also like terms, aren’t they? they all end in just a. So a is the common term it’s very common for a numeral, so again work with your coefficients only it’s going to be 12 minus 2 minus 7 and then we stick the an at the end so 12 minus 2 minus 7 you guys can calculate that it should be 3. So 3a is our answer okay? So again a does not change.

It’s a here, a here, a here so the answer should also just have a. Okay? That’s question three.
