Answer:
14.652c-21.22b
Step-by-step explanation:
multiply parentheses by -1.01
9.4c-22.22b+5.252c+b
collect like terms
14.652c-21.22b
In each quantity of 87 cg, 1 of them is active ingredient. In the quantity of interest,
... (1/87)·522 cg = 6 cg . . . is active ingredient
The remainder of that quantity, 516 cg, is inactive ingredient.
Use the formula: (a+b)(a-b) = a^2 - b^2
![x^4 - [(x^2)^2 - 1^2]\\\\x^4 - (x^4-1)\\\\x^4 - x^4 + 1\\\\\boxed{\bf{1}}](https://tex.z-dn.net/?f=x%5E4%20-%20%5B%28x%5E2%29%5E2%20-%201%5E2%5D%5C%5C%5C%5Cx%5E4%20-%20%28x%5E4-1%29%5C%5C%5C%5Cx%5E4%20-%20x%5E4%20%2B%201%5C%5C%5C%5C%5Cboxed%7B%5Cbf%7B1%7D%7D)
No matter what the value of 'x' is, the final answer will always be
1.
