Step-by-step explanation:

Aloha !

(x-1) (x+5) (x+8)(x+2) =880

(x²+5x-5-x)(x²+2x+8x+16)=880

(x²+4x-5)(x²+10x+16)=880

Thank you

$(x - 1)(x + 5)(x + 8)(x + 2) = 880 \\ ⇒ ({x}^{2} + 5x - x - 5)( {x}^{2} + 2x + 8x + 16) = 880 \\ ⇒ ({x}^{2} + 4x - 5)( {x}^{2} + 10x + 16) = 880 \\ ⇒ {x}^{4} + 10 {x}^{3} + 16 {x}^{2} + 4 {x}^{3} + 40 {x}^{2} + 64x - 5 {x}^{2} - 50x - 80 = 880 \\ ⇒ {x}^{4} + 14 {x}^{3} + 51 {x}^{2} + 14x - 80 = 880 \\ ⇒ {x}^{4} + 14 {x}^{3} + 51 {x}^{2} + 14x = 880 + 80 \\ ⇒ {x}^{4} + 14 {x}^{3} + 51 {x}^{2} + 14x = 960$
