10 ejercicos resueltos de exprecion algebraica !

Answer 1

1)      (X + 5/X + 2) + (4X + 5/X + 2)

 

X + 5 + 4X + 5/ X + 2

5X + 10/X + 2

5(X + 2)/X + 2

5

 

2)      (3/X + 1) – (1/X + 2)

 

3(X+2) – X – 1/(X + 1)*(X + 2)

2X – 5/X^2 + 3X + 2

 

3)      X^2 – 9/2X + 6

 

(X + 3) * (X – 3)/2 * (X + 3)

X – 3/2

 

4)      X^2 + 2X + 1/X^2 – 1

 

(X + 1)^2/(X + 1) * (X – 1)

X + 1/X – 1

 

5)      X^2 + X/X^2 + 2X

 

X * (X + 1)/X * (X + 2)

X + 1/X + 2

 

6)      6X^3 – 3X/3X

 

3X * (2X^2 – 1)/3X

2X^2 – 1

 

7)      -2X^2 + 8X – 8/4 – 2X

 

-2 *(X^2 – 4X + 4)/-2 * (X – 2)

(X – 2)^2/X – 2

X – 2

 

8)      (8/3X +1) * (5X + 2/6)

 

8 * (5X + 2)/6 * (3X + 1)

40X + 16/18X + 6

 

9)      6X + 30/8X + 40

 

6 * (X + 5)/ 8 * (X +5)

6/8

3/4

 

10)    X^2 – 4 / X + 2

 

(X + 2) * (X – 2)/X +2

X - 2
