Question

Calculati:
${x}^{6} - 5 {x}^{6} =$
$( - 4 {x}^{3}) \times ( - 3 {x}^{2}) =$
Dau coroana!!

Answer 1

x⁶(1-5)=(-4)(-3)x³⁺²
-4x⁶=12x⁵  |:(-4x⁵)
x=-3

Answer 2

$x {}^{6} (1 - 5) = ( - 4)( - 3) \times {}^{3} + {}^{2}$
$- 4 \times {}^{6} = 12 \times {}^{5} l \div ( - 4 \times {}^{5)}$
$x = - 3$
