Factor the expression completely. Begin by factoring out the lowest power of each common factor. 15x−1/2 + 8x1/2 + x3/2

Answer 1

It's really hard to tell what the problem is but I'll assume it is 15x^-1/2 + 8x^1/2 + x^3/2

x^-1/2(15 + 8x^2/2 + x^4/2)

x^-1/2(x² + 8x + 15)

x^-1/2(x + 5)(x + 3)

You can also write this as (x + 5)(x + 3)/x^1/2
