Question

(7x4 – 5x5 + 4x2 –7) + (x3 – 3x2 – 5 + x) – (–3x4 + 5 – 8x + 2x3)

Answer 1

Respuesta:

$(7 {x}^{4} - 5 {x}^{5} + 4 {x}^{2} - 7) + ( {x}^{3} - 3 {x}^{2} - 5 + x) - ( - 3 {x}^{4} + 5 - 8x + 2 {x}^{3} )$

$7 {x}^{4} - 5 {x}^{5} + 4 {x}^{2} - 7 + {x}^{3} - 3 {x}^{2} - 5 + x + 3 {x}^{4} - 5 + 8x - 2 {x}^{3}$

$10 {x}^{4} - 5 {x}^{5} - {x}^{3} - {x}^{2} + 9x - 17$

$5 {x}^{5} + 10 {x}^{4} - {x}^{3} - {x}^{2} + 9x - 17$
