Question

Разложите на множители a^2-6a+9
x^2+8x+16
a^3-8
b^3+27

Answer 1

Ответ:

$x {}^{2} + 8x + 16 \\ \\ x {}^{2} + 2 \times x \times 4 + 4 {}^{2} \\ \\ (x + 4) {}^{2}$

$a {}^{3} - 8 \\ \\ a {}^{3} - 2 {}^{3} \\ \\ (a - 2) \times (a {}^{2} + a \times 2 + 2 {}^{2} ) \\ \\ (a - 2) \times (a {}^{2} + 2a + 4)$

$b {}^{3} + 27 \\ \\ b {}^{3} + 3 {}^{3} \\ \\ (b + 3) \times (b {}^{2} - b \times 3 + 3 {}^{2} ) \\ \\ (b + 3) \times (b {}^{2} - 3b + 9)$
