Question

Holaa me podrían ayudar, de verdad necesito ayuda. ​

Answer 1

Respuesta:

$({a}^{2} + 8a - 3)( {11a}^{2} - 4a + 2 \\ {12a}^{2} + 4a - 1$

$(2mn - 5m {n}^{2} + {8m}^{2} n) (- 10mn - {6m}^{2} n + {3mn}^{2} + mn) = - 7mn + {m}^{2} n + 11 {mn}^{2}$

${x}^{2} - \frac{5}{5} \times + \frac{9}{5}$

$mn - 8mn + 3mn + {m}^{2} + {6m}^{2} - {2n}^{2} + {6n}^{2} + {4n}^{2} = - 4mn + {7m}^{2} + {8n}^{2}$
