(5x² - 10x + 5) - 6x² + 18x + 42 = x² - 3x - (2x) (x + 5) - 2
5x² - 10x + 5 - 6x² + 18x + 42 = x² - 3x - (2x² + 2 * 5x) - 2
- x² + 8x + 47 = x² - 3x - (2x² + 10x) - 2
- x² + 8x + 47 = - x² - 13x - 2
- x² + x² + 8x + 13x = - 2 - 47
21x = - 49
x = - 49/21
x = - 7/3
El valor de x es - 7/3
5(1-2x+x²)-6x²+18x+42=x²-3x-2x²-10x-2
5-10x+5x²-6x²+18x+42=-x²-13x-2
47+8x-x²=-x²-13x-2
8x+13x-x²+x²=-47-2
21x=-49
x=-49/21←Simplificar
x= -7/3
Espero que sirva!Saludos!
