1. Solución a ecuaciones.
a. 5t-22t2- 6t+9 - 11 t2- 3t =5t
5t-22 t-3t-3 *t-3 = 5t * t-3 + 11t t-3 * t-3
5t-22t-3 = 5t-15t + 11t5t-22t-3 = 5t-4t
t5t-22 = t-3 5t-4
5t2- 22t= 5t2-19t+12
5t2- 22t-5t2+ 19t = 12
- 3t = 12t = 12-3
t = - 4

b.1x2+3x+2 - 11-x = 2x2-4
4x+x2+1x-1x+2x+1 = 2x-2x+2
4x+x2+1x-1x+1 = 2x-2X+24x+x2+1 = 2x-1x+1
x3-7x-2 = -2
xx2-7 = 0
Así ±∞,-7, 0,7
c. 312-x-1x+1 = 149x+1-1
31x+1-2x-12x+1 = 149-1x+1x+1
3 x+1-2x+22x+1 = 149-x-1x+1
3-x+32x+1= 148-xx+1
-3x+92 = 8-x4
4-3x+9 = 28-x
-12x+36 = 16-2x-12x+2x = 16-36
-10x = -20
X = -20-10...
