En resumen
A) 2x + 5x - 10x + 4x = 12 7x - 6x = 12 x = 12 b) 2x + 10 - 1 + 5x = 24 7x = 24 - 9 x = 15 / 7 c) - 4x + 12 - 2 + 4 = 9 + x 14 - 9 = 5x x = 5 / 5 x = 1.
A) 2x + 5x - 10x + 4x = 12 7x - 6x = 12 x = 12
b) 2x + 10 - 1 + 5x = 24 7x = 24 - 9 x = 15 / 7
c) - 4x + 12 - 2 + 4 = 9 + x 14 - 9 = 5x x = 5 / 5 x = 1.
2x + 5x - 12 = 10x - 4x
7x - 12 = 6x
7x - 6x = 12
x = 12
2x - ( - 10 + 1) = 24 - 5x
2x + 10 - 1 = 24 - 5x
2x + 9 = 24 - 5x
2x + 5x = 24 - 9
7x = 15
x = 15 / 7 - 4x - ( - 12 + 2 - 4) = 9 + x - 4x - ( - 14) = 9 + x - 4x + 14 = 9 + x
14 - 9 = 4x + x
5 = 5x
5 / 5 = x
1 = x.

Sacas factor comun(x - y) (x - y)(a + b - c) listo.
a x c = b x b a x c = 10 b x b = 10 Entonces a x b x b x c 10 x 10 100.
Hay que ordenar los polinomios y si no estan completos , completar.
