Answer:
 5x^2+22x-12         x cannot be -5, -4, -2
(x+5)(x+4)(x+2)
Step-by-step explanation:
In order to solve this, your denominator must be the same. Let's start by writing out the two different quadratic formulas:
x^2 + 6x + 8 <-- This should factor out to (x+4)(x+2)
x^2 + 7x + 10 <-- This should factor out to (x+5)(x+2)
Now that you have factored out the two quadratics, plug them into the equation. 
     5x        -       3
(x+4)(x+2)      (x+5)(x+2)
Now as we know, -2 cannot be x because it will turn the entire equation undefined. Multiple top and bottom with (x+5) on the right side and (x+4) on the left side.
5x (x+5)             -           3(x+4)  
(x+5)(x+4)(x+2)      (x+5)(x+4)(x+2)
Focus on the top. 5x(x+5) will turn out to be 5x^2+25x. 3(x+4) will turn out to be 3x+12. Combine the two equations because now they are equal to each other and do the subtraction:
5x^2+25x - (3x+12)     =    5x^2+22x-12         x cannot be -5, -4, -2
  (x+5)(x+4)(x+2)               (x+5)(x+4)(x+2)
 
        
             
        
        
        
Answer:
the correct answer would be 5
Step-by-step explanation:
when c=7, then we put that value in for c in the equation c-2
c-2
(7)-2

Answer:
2204.4
Step-by-step explanation:
Okay so we want to always use order of operations: PEMDAS
Sop first we do what is in the parenthesis. 19*92 is 1748.
Now, going from left to right, we do multiplication and division. 76*32 is 2432. Then we divide that by 5 to get 486.4. And the last bit is 15*2 which is 30.
Your equation now is 486.4+1748-30.
The final answer is 2204.4
