Can somebody me with the steps to find the answer i don't know it at all

Will give brainliest sum of arithmetic series (sigma notation) find the numerical answer to the summation given below. (image shown below)

Graph the equationy=x^2 -[tex]y = x^{2} - 2[/tex]

Drag each expression to the correct location on the solution. not all expressions will be used. consider the polynomial 8x + 2x2 - 20x - 5. factor by grouping to write the polynomial in factored form.
