Question

${3x}^{4 } - {6x}^{3} +10 {x}^{2} \div - 2 {x}^{2}$
​

Answer 1

Explicação:

$3 {}^{4} - 6x {}^{3} + 10x {}^{2} \div ( - 2) \times x {}^{2} \\ \\ 3x {}^{4} - 6x {}^{3} - 5x {}^{2} \times x {}^{2} \\ \\ 3x {}^{4} - 6x {}^{3} - 5x {}^{4} \\ \\ - 2x {}^{4} - 6x {}^{3} \\ \\ = - 2x {}^{3} \times (x + 3)$
