$x\left( {x + 6} \right) = - 5$

2. misty1212

just trying to figure out what you wrote

3. misty1212

$x(x+6)=-5\\ x=-5\\ x+6=-5, x=-11$ something like that?

4. anonymous

yes

5. misty1212

the error is that if $$x(x+6)=-5$$ then it does not follow that one of those factors is $$-5$$ we can only use that if it is set equal to zero i.e. if the product of two factors are zero, one of the factors must be zero
