Answer 2

Do the following divisions.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\sf - 20x {}^{4} \div 10 {}^{2} = - 2 \times 2 \times 5 \times x \times x \times x \times x$

$\sf10x {}^{2} = 2 \times 5 \times x \times x$

Therefore,

$\sf( - 20x {}^{4}) \div 10 {x}^{2} = \frac{ - 2 \times 2 \times 5 \times x \times x \times x \times x}{2 \times 5 \times x \times x}$

${\boxed{ \sf{ = - 2 \times x \times x = - 2x {}^{2}}}}$
