2(9x-1)+7(x+6)=-60
Reorder the terms in parentheses
+(+18x-2)+7*(x+6)=-60
Remove unnecessary parentheses
+18x-2+7*(+x+6)=-60
Reorder the terms in parentheses
+18x-2+(+7x+42)=-60
Remove unnecessary parentheses
+18x-2+7x+42=-60
We move all terms containing x to the left and all other terms to the right
+18x+7x=-60+2-42
We simplify left and right side of the equation
+25x=-100
We divide both sides of the equation by 25 to get x
x=-100/25
x=-4

Where x and y are perfect square expressions.

From the list of options, we have:

25a^2-36b^6

The terms of the above expression are perfect squares

25a^2 = (5a)^2

36b^6 = (6b^3)^2

Hence, the difference of two squares expression is (d) 25a^2-36b^6
