Question

expresión algebraica de (x-2)(x+3)
A)x²+x-6
B)x²-5
C)x²+x+6
D)x²+3x​

Answer 1

Resolver las expresiones algebraicas :

A) Resolver “x² + x - 6"

$x {}^{2} + x - 6$

$a + b = 1$

$ab = 1( - 6) = - 6$

$- 1.6$

$- 2.3$

$- 1 + 6 = 5$

$- 2 + 3 = 1$

$a = - 2$

$b = 3$

$(x {}^{2} - 2x) + (3x - 6)$

$x(x - 2) + 3( x - 2)$

$(x - 2)(x + 3)$

B) Resolver “x² - 5"

$x {}^{2} - 5$

$2x {}^{2 - 1}$

$2x {}^{1}$

$2x$

C) Resolver “x²+ x + 6"

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

$2x {}^{2 - 1} + x {}^{1 - 1}$

$2x {}^{1} + x {}^{1 - 1}$

$2x {}^{1} + x {}^{0}$

$2x + x {}^{0}$

$2x + 1$

D) Resolver “x² + 3x"

$x {}^{2} + 3x$

Simplifica “x"

$x(x + 3)$

RPTA: (x - 2) (x + 3)

x² + 3x -2x - 6

x² + x - 6

Entonces, La opción sería la “a"
