Answer:

2.) 3/8

3.) 3/8

4.) Couldn't read this one, too blurry

5.) 5/12

6.) 3/10

7.) 5/12

8.) 1/8

9.) 1/5

10.) 1/8

11.) 1/4

Step-by-step explanation:

So the thing about subtracting fractions is that you have to have the same denominator for both of them. (that's the number on the bottom.) So number 3 is 7/8 - 1/2. You're gonna wanna multiply 1/2 by four, for both the top and bottom number. This creates 4/8. Now you can subtract them! 7-4 = 3, and thus the answer is 3/8. You never, <em>ever</em> subtract the denominator: only the numerator.

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "c2"   was replaced by   "c^2".  1 more similar replacement(s).

Step by step solution :<span>Step  1  :
</span><span>Equation at the end of step  1  :</span><span><span> ((((4•(c2))+6c)-3c2)-2c)-3 </span><span> Step  2  :</span></span><span>Equation at the end of step  2  :</span><span> (((22c2 + 6c) - 3c2) - 2c) - 3 </span><span>Step  3  :</span>Trying to factor by splitting the middle term

<span> 3.1 </span>    Factoring <span> c2+4c-3</span> 

The first term is, <span> <span>c2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> +4c </span> its coefficient is <span> 4 </span>.
The last term, "the constant", is <span> -3 </span>

Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -3 = -3</span> 

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is  <span> 4 </span>.

<span><span>     -3   +   1   =   -2</span><span>     -1   +   3   =   2
