Question

5 ECUACIONES DEMATMATICAS =)

Answer 1

1)3x+6-5=2x+2

3x-2x=2-6+5

x=1

2)6x + 18 - 9x + 3 = 12x + 6

6x - 9x - 12x = 6 -18 - 3

-15x = -15

x = -15/-15 = 1

3)4x2-64=0

4x2 = 64

x2 = 64/4 = 16

4)5x2-125x = 0

x(5x- 125)=0

x=0 5x- 125=5

5x = 125

x = 125/5 = 25

5)x2 - 4 + 5x = 5x + 5

x2 -4 + 5x - 5x - 5 = 0

x2 - 9 = 0 (Incompleta de tipo I)

x2 = 9

x = ±3
