2 x - 7*x
x^2 - 7*x
Differentiate x2−7xx^{2} - 7 xx2−7x term by term:
Apply the power rule: x2x^{2}x2 goes to 2x2 x2x
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: xxx goes to 111
So, the result is: −7-7−7
The result is: 2x−72 x - 72x−7
The answer is:
-7 + 2*x
