Answer:
-1
Step-by-step explanation:
You can write it as...

Carry the 4x

Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have

Therefore our answer is -1
 
        
             
        
        
        
First combine like terms and put the expression in standard form. This expression is now in simplest form and cannot be simplified anymore.
3a + 10ab - 7a^2b - 10ab^2 + 12ab - (-4) + (-a^2b) - 5a 
-10ab^2 - 8a^2b -2a + 24ab - (-4)
Hope this helps
