1. Answer:

x =

Step-by-step explanation:

We know that we have to find the roots of the equation – which is another way of saying the x-intercepts, or the points that are on the x-axis that the graph passes through. All points on the x-axis have a y-value of 0. So, in order to find the roots for this equation, we need to find which values of x make the y equal 0.

The equation has already been factored out. So, we just need to find which values of x for each of the expressions in the parentheses will make the result 0. To do this, set the expressions in the parentheses to 0 and isolate x.

1) First, let’s look at (2x-3). Write the equation 2x-3 = 0. Then, isolate x:

Therefore, is one of the roots.

2) Next, let’s look at (x+5). Write the equation x+5 = 0. Then, isolate x:

Therefore, -5 is a root as well.

The roots of the equation would be and -5.
