Let's find the discriminant of <span>x^2+9x+14=0.  Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac.  Substituting the above numeric values,
                                9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5.  Thus, your polynomial has two unequal, real roots.
Off the point example:  If the discriminant were zero, your poly would have two real, equal roots.</span>
        
             
        
        
        
Answer:Hlello, my name is woods245.
So you have the problem b - 3>5 and is says that b=6. 
So know the problem looks like this. 6 - 3>5.

Answer: a = -5
Step-by-step explanation:
First, open up the brackets, and solve it
-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)
bring the -8a to the left side, so that all the a’s are together
-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)
-12a + 8a = -22 + 42
solve
-4a = 20
divide -4 on both sides
a = -5
 
        
                    
             
        
        
        
7/8 into a decimal is 0.875
hope it helps!!
        
             
        
        
        
Hey there :)
9( n - 4 ) - 4n ( n - 4 )
We can take ( n - 4 ) as common as both are getting multiplied by ( n - 4 )
We can join 9 - 4n together
Therefore, the final answer will be ( n - 4 )( 9 - 4n )
