well you minus 2 from the four and you get 2x(x)=14 then you get 2 squared=14 and 2 squared is not 14 so it is incorrect.
this is a quadratic equation, I am not quite sure what you were trying to do/
everything that has been posted still makes no sense im confused
I need to find what's wrong with the problem and correct it
kitto are you sure this is exactly how they asked the question?
you asked if a statement with a variable is true. this statement is only true for 2 x values, those are the ones I showed at the end...
you could have gotten the same answers from
there is nothing wrong with the problem
this is sort of like asking this...
is this statement true
2+x = 4
well this is true when x = 2
4 x (x + 2) = 14
4x + 2 =14
4x == 12
you need to read about quadratic equations
4x(x+2) by the distribution propertiy of multiplication is
so you have
we set equal to 0 and then solve
now we can use the formula I showed
a = 4
b = 8
c = -14
if this were true when x = 3 as you said then
\[4*3(3+2) = 12(5) = 60\ne14\]
