Final answer:
To simplify the complex fraction x + 15 / 8(x - 1), multiply both the numerator and denominator by the LCD of the fractions and cancel out like terms.
Step-by-step explanation:
To simplify the complex fraction x + 15 / 8(x - 1), we can start by finding the LCD (Least Common Denominator) of the fractions in the numerator and denominator.
The LCD of the fractions x + 15 and 8(x - 1) is 8(x - 1).
Multiplying both numerator and denominator by the LCD, we get (x + 15) * 8(x - 1) / [8(x - 1)].
Simplifying further, we have (x + 15) * 8(x - 1) / 8(x - 1). The 8(x - 1) terms in the numerator and denominator cancel out, leaving us with the simplified form of the complex fraction as x + 15.
