Cross and multiply which should get you 4x=45 then divid 4 to each side and the answer should be x=11.25
Note --> As you're writing 'zeroes' , I assume there is a typing mistake and you've given a Quadratic equation in the question

Hence , the roots are 1/2 and -6
The graph attached confirms the same ,
Hope it helps you :)
It’s (-2 , -2)
It has to be that answer
