Question

Por favor es pa un examen

Answer 1

$(2 + c)x^{4} +x^{4}+(c -4)x^{9-c} +3x^{4} \\\\2x^{4} +cx^{4} + x^{4}+ cx^{9-c} - 4x^{9-c} + 3x^{4}\\\\ 2x^{4} +cx^{4} + x^{4}+ cx^{9}.x^{-c} - 4x^{9}.x^{-c} + 3x^{4}\\\\6x^{4} +cx^{4} + cx^{9}.x^{-c} - 4x^{9}.x^{-c}$

Como son términos semejantes

9 - c = 4

9-4 = c

5 = c

$6x^{4} +5x^{4} + 5x^{9}.x^{-5} - 4x^{9}.x^{-5}\\\\6x^{4} +5x^{4} + 5x^{9-5} - 4x^{9-5}\\\\6x^{4} +5x^{4} + 5x^{4} - 4x^{4}\\\\12x^{4}$

Eternamente axllxa
