Answer:
 x2-5x-8=0  
Step-by-step explanation:
Two solutions were found :
 x =(5-√57)/2=-1.275
 x =(5+√57)/2= 6.275
Reformatting the input :
Changes made to your input should not affect the solution:
 (1): "x2"   was replaced by   "x^2".  
Step by step solution :
Step  1  :
Trying to factor by splitting the middle term
 1.1     Factoring  x2-5x-8  
The first term is,  x2  its coefficient is  1 .
The middle term is,  -5x  its coefficient is  -5 .
The last term, "the constant", is  -8  
Step-1 : Multiply the coefficient of the first term by the constant   1 • -8 = -8  
Step-2 : Find two factors of  -8  whose sum equals the coefficient of the middle term, which is   -5 .
     -8 + 1 = -7  
     -4+  2 = -2  
     -2+  4	= 2  
     -1	+   8	= 7  
 
        
                    
             
        
        
        
Answer:
x = 5
y = 9
Step-by-step explanation:
Since the scale is 2, the side of x needs to 4 because the corresponding side on the other figure is 2 (2 * 2 = 4).
So, x - 1 = 4
x = 5
Similar to the y side, the y side needs to be 10.
So, y + 1 = 10
y = 9
 
        
             
        
        
        
Step-by-step explanation:
Distribute:
=−x2+−4x+−4+7
Combine Like Terms:
=−x2+−4x+−4+7
=(−x2)+(−4x)+(−4+7)
=−x2+−4x+3
Answer:
=−x2−4x+3
