Question 427652
solve for x
  
4x(x-4)-5x(x-3)=0

Multiply on the left side using FOIL method

4x^2 - 16x - 5x^2 + 15x = 0

Collect the like terms:

(4x^2 -5x^2) + (-16x +15x) = 0
-x^2 -x = 0

Factor it out

-x(x+1)=0

Use the zero product property to solve for x:

-x = 0 OR x + 1 = 0

You can get it from here. Remember to check your answers!
