## Best Answer - Chosen by Voters

(x-2)(2x+5)=0
x - 2 = 0 or 2x + 5 = 0
x = 2 or x = -5/2
The smaller of 2 and -5/2 is -5/2.

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:
x-2=0
x-2+2=0+2
x=2
--------------
2x+5=0
2x+5-5=0-5
2x=-5
x=-5/2
x=-2.5
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 :)

(x-2)(2x+5)=0
2(x+5/2)(x-2)=0
x1=2
x2=-5/2
x=-5/2 - the smaller value
