Answer:
6x^2 +81x - 17
---------------------
7x-15
Step-by-step explanation:
We cannot solve for x since this is an expression
((6x+9) (x+12) -sqrt(49+76) ^2
--------------------------------------------
(49+7x) -64
Lets simplify the numerator
((6x+9) (x+12) -sqrt(49+76) ^2
Simplify what is inside the last parentheses
((6x+9) (x+12) -sqrt(125) ^2
Squaring a square root leaves the original number
((6x+9) (x+12) -(125)
FOIL the first two terms
First 6x*x = 6x^2
Outer: 6x*12 = 72x
Inner: 9x
Last : 9*12 = 108
Add them together
6x^2 +72x+9x+108 = 6x^2 +81x+108
Subtract the 125
6x^2 +81x+108-125
6x^2 +81x - 17
Now lets simplify the denominator
(49+7x) -64
49+7x-64
7x-15
6x^2 +81x - 17
---------------------
7x-15
