Question

(x+3)2+2(x-3)+1 ayudaaaaaaaaa porfavorrr

Answer 1

Respuesta:

$(x + 3)2 + 2(x - 3) + 1 \\ 2x + 6 + 2x - 6 + 1 \\ 4x + 1$

$o \: tal \: vez \: era \: \\ \\ (x +3 )2 + 2(x - 3) = 1 \\ 2x + 6 + 2x - 6 = 1 \\ 4x = 1 \\ x = \frac{1}{4} \\ \\ comprobacion \\ ( \frac{1}{4} + 3)2 + 2( \frac{1}{4} - 3) = 1 \\ \\ ( \frac{1 + 12}{4} )2 + 2( \frac{1 - 12}{4} ) = 1 \\ \\ (\frac{13}{4} ) \times 2 + 2 \times ( - \frac{11}{4} ) = 1 \\ \\ \frac{26}{4} + ( - \frac{22}{4} ) = 1 \\ \\ \frac{26}{4} - \frac{22}{4} = 1 \\ \\ \frac{4}{4} = 1 \\ \\ 1 = 1$
