в (4b²-5b+2)*36
г x³(x²-3x+1)

Answer 1

Answer 2

$3x(4x {}^{3} - 2x) \\ 3x \times 4x {}^{3} - 3x \times 2x \\ 12x {}^{4} - 6x {}^{2}$

$- 5a {}^{2} (a {}^{3} - 6a + 2) \\ - 5a {}^{2} \times a {}^{3} - 5a {}^{2} \times ( - 6a) - 5a {}^{2} \times 2 \\ - 5a {}^{5} + 30a {}^{3} - 10a {}^{2}$

$(4b {}^{2} - 5b + 2) \times 36 \\ 4b {}^{2} \times 36 - 5b \times 36 + 2 \times 36 \\ 144b {}^{2} - 180b + 72$

$x {}^{3} (x {}^{2} - 3x + 1) \\ x {}^{3} \times x {}^{2} - x {}^{3} \times 3x + x {}^{3} \\ x {}^{5} - 3x {}^{4} + x {}^{3}$
