(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)
The negative sign separating the expressions is just multiplying the rightmost expression by -1.
(2x^2 + 4x + 6) + (3x + 5x^2 - 4)
Now, let's add together terms that share the same variable.
2x^2 + 5x^2 = 7x^2
4x + 3x = 7x
6 + (-4) = 2
Let's combine each of these terms into one expression.
7x^2 + 7x + 2 is the final answer.
Step-by-step explanation:
I think that X2 should be x squared
When multiplying two numbers, a person can mentally add one of those numbers the other number amount of times.
Answer:
Where is the fourth diagram?
" always " is the wrong word....should be sometimes
usually the LCM is greater....
example : 2 and 4.....LCM = 8, GCF = 2
3 and 6....LCM = 12, GCF = 3
However, if ur 2 numbers are the same...
2 and 2.....LCM = 2 and GCF = 2
4 and 4....LCM = 4 and GCF = 4
