Answer:
The roots of the polynomial equation in this case would be the intersection of the 2 polynomial functions. which are at x = 4 and x = -3
Step-by-step explanation:
The roots are found by finding the x-values of the intersections of these two cubic polynomial functions.
We could try solving algebraically, but you have the graph.
10x-20=10x-20, make your decision on the answer from this which they are all real numbers. Hope this will help you!
You find a common denominator (the bottom one) and then add the numerator (the top) but you don't add the denominator, you just make it the same
