Answer: x - 5/x + 1
Step-by-step explanation:
This algebraic fraction
The task to be performed here is factorisation and simplification. Now going by the question, 
x² + 4x - 45/x² + 10x + 9, the factorisation of 
x² + 4x - 45 = x² + 9x - 5x - 45 
 = x(x + 9 ) - 5(x + 9 )
 = ( x + 9 )(x - 5 ), don't forget this is the algebraic fraction's Numerator
The second part 
x² + 10x + 9 = x² + x + 9x + 9
 = x(x + 1) + 9( x + 1 )
 = ( x + 9 )( x + 1 ), this is the algebraic denominator.
Now place the second expression which is the denominator under the first expression which is the numerator.
 ( x + 9 )( x - 5 )/( x + 9 )( x + 1 ).
You can see that, ( x + 9 )/( x + 9 ) divide each other , therefore therr then cancelled and left with
 x - 5/x + 1
