Reorder the terms:
17 + 8x = (x + 3)(8x + 17)

Reorder the terms:
17 + 8x = (3 + x)(8x + 17)

Reorder the terms:
17 + 8x = (3 + x)(17 + 8x)

Multiply (3 + x) * (17 + 8x)
17 + 8x = (3(17 + 8x) + x(17 + 8x))
17 + 8x = ((17 * 3 + 8x * 3) + x(17 + 8x))
17 + 8x = ((51 + 24x) + x(17 + 8x))
17 + 8x = (51 + 24x + (17 * x + 8x * x))
17 + 8x = (51 + 24x + (17x + 8x2))

Combine like terms: 24x + 17x = 41x
17 + 8x = (51 + 41x + 8x2)

Solving
17 + 8x = 51 + 41x + 8x2

Solving for variable 'x'.
