sinve you are multiplying the two brackets together to equal 0 then one of the two brackets must equal 0.
You can seperate the equation into two halves: x-2=0 and 2x+5=0
you then solve for both of them and whichever has a lesser value is your answer:
Since -2.5 is less than 2 the smaller value of x is -2.5
Hope this helps. If you have any further questions feel free to email me :)
