You can put this solution on YOUR website! x=0 if you plug your equation into the quadratic calculater it will give you the full explanation if you want- this is just the final answer
You can put this solution on YOUR website! This is a trick problem to see if you understand equations.
.
If you multiply out the left side of this equation and add the + 56 the left side of the equation is:
.
.
Next, if you multiply out the right side of the equation you get:
.
.
So, putting together the left and right sides the equation is:
.
.
This is an identity equation. The left side always equals the right side. Notice that if you cancel the like terms on both sides the equation reduces to:
.
.
What does this mean? It means that the original equation of the problem will be satisfied for all values of x. Pick any value for x, substitute it into all the x terms on both the left and right sides and both sides of the equation will be equal to each other.
.
As an easy example, let's choose x = 0. The left side of the original equation becomes:
. and this reduces to just
.
and the right side of the original problem becomes:
. and this becomes just
.
So the left side equals the right side. Next we can try it for some value of x that is not too difficult ... say x = +1. Substituting +1 for x the equation reduces to:
.
.
and this further reduces to:
.
.
You might want to try a few other values for x, but the result will always be the same whether the value of x is positive or negative. Whatever value you choose, the left side will work out to be the same value as the right side. That's the property of an identity equation.
.
Hope this helps you to understand this problem a little better.
