%282x%2B2%29%285x-5%29=0 Start with the given equation



Now set each factor equal to zero using the zero-product property:

2x%2B2=0 or 5x-5=0


Let's solve the first equation 2x%2B2=0:


2x%2B2=0 Start with the first equation.


2x=0-2 Subtract 5 from both sides.


2x=-2 Combine like terms on the right side.


x=-2%2F2 Divide both sides by 2 to isolate x.


x=-1 Reduce


So the first solution is x=-1

----------------------------------------------------------------

Now let's solve the second equation 5x-5=0


5x-5=0 Start with the second equation.


5x=0%2B5 Add 5 to both sides.


5x=5 Combine like terms on the right side.


x=%285%29%2F%285%29 Divide both sides by 5 to isolate x.


x=1 Reduce.


So the second solution is x=1



So the solutions are x=-1 or x=1
