1 What is the solution to the equation
x
X+ 3
2x2
x
2
x=-3
x= -3 and x = 0
x = 0 and x = 3
x = 3
Is this answer correctly

x=3

Step-by-step explanation:

1/x  = (x+3)/ 2x^2

Using cross products

1*2x^2 = x(x+3)

2x^2 = x^2 +3x

Subtract x^2 from each side

2x^2 -x^2 = 3x

Subtract 3x from each side

x^2 -3x =0

Factor

x(x-3) = 0

Using the zero product property

x=0  x-3 =0

x=0   x=3

Checking the solutions

x cannot be zero since the denominator cannot be zero

x=3

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
