Please verify that I did this long division correctly. Pleas verify that I wrote the quotient correctly, I'm not sure if I wrote the Remainder correctly. Please check, thanks!

Please verify that I did this long division
3. Divide using long division. (8x3+ 3x2 - 5x - 7) : (x2 -1). Use the quotient to write the dividend in P(x) = D(x) Q(x) + R(x) form. 8 x + 3 x 2 8x3 + 3x3 - 5x - 7 8 x3 1 - 8x 1 3x 2 + 3x - 7 3 x2 - 3 3X - 4 3x - 4 Quotient: 8x+3+ x2 - 1 P(x) = D(x) Q(x) + R(x) form; 8x3-+3x2 -5x-7 = (X2 -1) (8x+3)+3x-4
