Question

Which statement below best applies to the following expression?

Answer 1

A.
the two terms cannot be combined because the radicands are not identical, and cannot be simplified so that they are identical
B.
the two terms cannot be combined because the indices are not identical
C.
the two terms cannot be combined because the resulting value of the subtraction would be negative
D.
the two terms may be combined

Answer 2

@Hero

Answer 3

help plz

Answer 4

@Dragonclaw88, What are your own thoughts regarding the expression?

Answer 5

i dont have any i just need to know how to solve it

Answer 6

i guess that counts right?

Answer 7

What if you had -4x - 5y. How would you combine that expression?

Answer 8

ummmm......i think you combine the numbers first right?

Answer 9

Ever heard of the concept of combining like terms? If so, what does it mean to you?

Answer 10

ik what it is im just not very good at actually doing it

Answer 11

what u gave me where unlike terms

Answer 12

im not sure how to combine those

Answer 13

Well, let me give you an idea of it.

7 + 8 = 15
7 and 8 are like terms because they are both integers

2x + 4x = 6x

2x and 4x are like terms because x is common to both. In fact, if we use the distributive property, then
2x + 4x = (2 + 4)x = (6)x = 6x

7xy + 3xy = 10xy

Same concept here.

5x^2 + 3x^2 = 8x^2

See the pattern?

You can only combine terms if they have common variable factors.

Answer 14

With radicands, you treat those as variable factors.

Answer 15

BEFORE YOU GAVE ME UNLIKE TERMS AND TOLD ME TO COMBINE THEM BUT I DON'T KNOW HOW!!!!!
sorry to be rude....

Answer 16

i know how to combine like terms that is easy

Answer 17

So you can combine something like \(6\sqrt{5} + 3\sqrt{5}\) but it is not possible to combine \(3\sqrt{5} + 4\sqrt{7}\). In other words, when it comes to radicals, the concept of like terms apply here as well.

Answer 18

i have no idea how to combine radicals at all i failed algebra 1 because i dont understand many concepts of anything

Answer 19

Re-read everything I wrote above, but more slowly this time. I'd also recommend taking a break and coming back later or even taking a short nap while thinking about the concept here. It will help.
