Final answer:
To split the middle term -5x into (-8x + 3x), find two numbers whose product is equal to the product of the coefficient of the x term (-5) and the constant term (1) in the denominator. Rewrite the middle term as -8x + 3x and continue simplifying the expression.
Step-by-step explanation:
To split the middle term -5x into (-8x + 3x), we need to find two numbers whose product is equal to the product of the coefficient of the x term (-5) and the constant term (1) in the denominator. The numbers in this case are -8 and 3. We then rewrite the middle term as -8x + 3x and continue simplifying the expression.
