Step by step solution :
Step  1  :
Equation at the end of step  1  :
  ((3x2 +  2x) -  1) -  (x2 - 3x + 4)
Step  2  :
Trying to factor by splitting the middle term
 2.1     Factoring  2x2+5x-5 
The first term is,  2x2  its coefficient is  2 .
The middle term is,  +5x  its coefficient is  5 .
The last term, "the constant", is  -5 
Step-1 : Multiply the coefficient of the first term by the constant   2 • -5 = -10 
Step-2 : Find two factors of  -10  whose sum equals the coefficient of the middle term, which is   5 .
      	-10     +    	1     =    	-9  
      	-5     +    	2     =    	-3  
      	-2     +    	5     =    	3  
      	-1     +    	10     =    	9  
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
  2x2 + 5x - 5

Answer:
D
Step-by-step explanation:
Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line
 
        
                    
             
        
        
        
You put a variable for unknown numbers. 5. 96-x and 6. 17+x
        
                    
             
        
        
        
Answer:
0.2 < x < 11.8
Step-by-step explanation:
The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side, for it to form a triangle. So, we can set up 3 equations, x + 5.8 > 6, 5.8 + 6 > x, and x + 6 > 5.8. This solves out to x > 0.2, x < 11.8, and x > -0.2. We can disregard that last one, because a side can't be negative. Therefore, we know the possible range of values for x.
