anonymous · Answer

to have a quadratic equasion, you fist need to set one side = to 0

anonymous · Answer

subtract 2(x-2) from both sides

anonymous · Answer

5x^2 + 4x + 3 = 0 is what u get

anonymous · Answer

@grandzam   
btw it's 
subtract 2(x+2) from both sides

anonymous · Answer

eh that was a mistake. But I did the work right

anonymous · Answer

so it is 3? right? @MrNood

@GracieFerrell 
Do you understand what @grandzam did above?

You need to get the equation into the form 
ax^2+bx+c=0

if you can see how he did that , then you can see whether his answer is correct...
