Question

03. Efetue:
a) 2x² + 3x + 4x
b) 4x² - 8x² +6x² + x?
04. Calcule:
a) x2 + x + x =
b) (4x). (3x) =​

Answer 1

Resposta:

$a)2x^{2} + 3x + 4x \\ x(2x + 7) \\ 2x + 7 \\ x = (2x + 7)$

$b)4x^{2} - {8x}^{2} + {6x}^{2} + x \\ { - 4x}^{2} + {6x}^{2} + x \\ {2x}^{2} + x$

$4.a)x2 + x + x = 2x+x_{2} \\ b)(4x) \times (3x) \\ {4x}^{2} \\ 12x^{2}$
