Question

operación (7w3-2w2+11w)-( -4w3+3w2+2w-1)​

Answer 1

Respuesta:

$11 {w}^{3} - 5 {w}^{2} + 9w + 1$

Explicación paso a paso:

$7 {w}^{ 3} - 2 {w}^{2} + 11w - ( - 4 {w}^{3} + 3 {w}^{2} + 2w - 1) \\ 7 {w}^{ 3} - 2 {w}^{2} + 11w + 4 {w}^{3} - 3 {w}^{2} - 2w + 1 \\ 11 {w}^{3} - 5 {w}^{2} + 9w + 1$

Answer 2

Respuesta:

$\frac{11(2w^{4} +2w^{2}  -91)}{2w}$

Explicación paso a paso:

$= 7w^{3}-2w^{2}+11w -(-4w^{3}+3w^{2}+ 2w^{-1})\\=  7w^{3}-2w^{2}+11w + 4w^{3}-3w^{2}- 2w^{-1}\\= 11w^{3} -5w^{2} +(11w-\frac{1}{2w} )\\=11w^{3} - 5w^{2} + \frac{22w^{2}-1 }{2w} \\=11w^{3} - \frac{10w^{3}-22w^{2} +1}{2w} \\=\frac{11(2w^{4} +2w^{2}  -91)}{2w}$
