Question

Resolva as operações:

a) x²+x-3x²+4x-3x=
b) (-12x³y)÷(2xy)=
c) (2x²y).(-4ax)=
d) (-2x³)²=

Answer 1

$x {}^{2} + x - 3x {}^{2} + 4x - 3x \\ - 2x {}^{2} + x + 4x - 3x \\ - 2x {}^{2} + 2x \\ - 2x \times (x - 1) \\ \\ ( - 12x {}^{3} y) \div (2xy) \\ 6x {}^{2} \\ \\ (2x {}^{2} y) \times ( - 4ax) \\ - 2x {}^{2} y \times 4ax \\ - 8ax {}^{3} y \\ \\ ( - 2x {}^{3} ) {}^{2} \\ ( - 2) {}^{2} \times (x {}^{3} ) {}^{2} \\ 4x(x {}^{3}) {}^{2} \\ 4x {}^{6}$
