Given : Expression 
To find : What is the value of x?
Solution :
Step 1 - Write the expression,

Step 2 - Cross multiply,

Step 3 - Take like terms together,

Step 4 - Solve,



Therefore, The value of x is -10.
Use the power rule
d(x^n)/dx = n·x^(n-1)
to form the derivative.
f'(x) = 4·2x -4
f'(x) = 8x - 4
Now, substitute "a" for "x" to find f'(a):
f'(a) = 8a - 4
