Find x in the following right triangle

a squared + b squared = c squared

576+100=c squared

676=c squared

c squared = 26

hope it helps

If you observe the graph, the graph is touching the x-axis at the point x=-1 and is turning away. 

This means, the graph as an even multiplicity at x=-1. So the two roots of the given polynomial are x = -1 and x = -1. Thus, the two factors of the polynomial are (x+1) and (x+1)

Product of the factors is equal to the polynomial. So the given polynomial will be (x+1)(x+1).

Therefore, the answer to this question is option C
