2 x + x + 4
x^2 + x + 4
Differentiate (x2+x)+4\left(x^{2} + x\right) + 4(x2+x)+4 term by term:
Differentiate x2+xx^{2} + xx2+x term by term:
Apply the power rule: x2x^{2}x2 goes to 2x2 x2x
Apply the power rule: xxx goes to 111
The result is: 2x+12 x + 12x+1
The derivative of the constant 444 is zero.
The answer is:
1 + 2*x
2
