Question 73624
The question says solve:
{{{x(x+1)= -2(x-4)=2}}}<---typing error - the second = sign is supposed to be "+"
.
This is what I did, can you tell me if I am on the right track, please?
.
{{{x(x+1)= -2(x-4)=2}}} <--- same comment as above. you correct this OK in the next step
{{{x*2+1x= -2x+8+2 }}}<--- no need to show the 1 as the multiplier of x. 
{{{x*2+x+2x-8-2=0 }}}<--- OK
{{{x*2+3-10=0}}} <--- should be +3x, not just 3
{{{(x+5)*(x-2)}}} <---- should show this product as equal to 0
{{{x+5=0}}}{{{ x-2=0 }}}<---- OK
{{{x=-5}}} and {{{x=-2}}} <--- the x = -5 is correct but you have a very minor mistake in 
saying x = -2.  Check your work on solving x-2 = 0.

Good job! You seem to understand all the steps you have to do to solve this equation, and
you also understand factoring quadratic equations.
