U R G E N T E fatore as expressões algébricas : 1. 2b+4c 2. 20x²+5x+x 3. 6x³-3x²+9x 4. 2x²+4y-8 5. 2a+4b-6c

Answer 1

Oie, Td Bom?!

1.

$= 2b + 4c$

$= 2(b + 2c)$

2.

$= 20x {}^{2} + 5x + x$

$= 20x {}^{2} + 6x$

$= 2x \: . \: (10x + 3)$

3.

$= 6x {}^{3} - 3x {}^{2} + 9x$

$= 3x \: . \: (2x {}^{2} - x + 3)$

4.

$= 2x {}^{2} + 4y - 8$

$= 2(x {}^{2} + 2y - 4)$

5.

$= 2a + 4b - 6c$

$= 2(a + 2b - 3c)$
