Answer 1

Answer:

$(8x^{2} -13x-5)(x^{2} -3x+10)\\8x^{2}(x^{2} -3x+10)-13x(x^{2} -3x+10)-5(x^{2} -3x+10)\\8x^{4} -24x^{3} +80x^{2} -13x(x^{2} -3x+10)-5(x^{2} -3x+10)\\8x^{4} -24x^{3} +80x^{2} -(13x^{3} -39x^{2}+130x)-5(x^{2} -3x+10)\\8x^{4} -24x^{3} +80x^{2} -(13x^{3} -39x^{2}+130x)-(5x^{2} -15x+50)\\8x^{4} -24x^{3} +80x^{2} -13x^{3} +39x^{2}-130x-5x^{2} +15x-50\\8x^4+(-24x^3+13x^3)+(80x^2+39x^2-5x^2)+(-130x+15x)-50\\8x^4-37x^3+114x^2-115x-50$

Answer 2

Answer:

8x^4-24x^3+80x^2-3x^3+39x^2-130x-5x^2+15x-50

8x^4-24x^3-13x^3+80x^2-5x^2+39x^2-130x+15x-50

8x^4-37x^3+114x^2-115x-50

hope this helps you out
