Answer 1

See below

Explanation:

Multiply left side of equation by x/x ( this is just multiplying by '1')

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

Now, subtract underlined portion from both sides

1 = (1-x^2) / (x^2 + 3x) multiply by x^2 + 3x

x^2 + 3x = 1 - x^2

2x^2 + 3x -1 = 0 Use Quadratic formula to find x = -3/4 +- sqrt(17)/4
