Answer:
The middle term would be 48x
Step-by-step explanation:
In order to find this, we need to take the squares of the end terms and put them in a perfect square. Then we can distribute to find the middle term.
(3x + 8)^2
(3x + 8)(3x + 8)
9x^2 + 24x + 24x + 64
9x^2 + 48x + 64
You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-
= √7 ( 5 + √2) / (5 - √2)(5 + √2)
= √7 ( 5 + √2) / (25 -2)
= (√7 ( 5 + √2)) / 23 answer
