Question

x square + x = 2 verify !!​

Answer 1

$\tt{ {x}^{2} + x = 2}$

$\tt{x(x + 1) = 2}$

$\tt{x + 1 = \frac{2}{x} }$

$\tt{x = \frac{2}{x} - 1 }$

$\tt{x = \frac{2 - x}{x} }$

Answer 2

Answer:

x=1 and x=-2

Step-by-step explanation:

$x ^{2} + x = 2$

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

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

$x(x - 1) + 2(x - 1) = 0$

$(x + 2)(x - 1) = 0$

$x + 2 = 0 \: and \: x - 1 = 0$

$x = - 2 \: \: \: and \: \: \: x = 1$
