Anyone ? what is the derivative of x^2 + 2x - 4? !

D/dx(x² + 2x - 4) = 2x + 2

d/d (x² + 2x - 4) 

= d/dx (x²) + d/dx(2x) - d/dx(4)

= d/dx(x^2) - d/dx(2x) = 2x (due to power rule)

Replug in to equation
d/dx (2x) = 2

Take the constant out

d/dx (x) = 1

apply the common derivative

2 x 1

simplify 

2 x 1 = 2

d/dx(4) = 0

d/dx(4)

drivative of a constant = 0

= 2x + 2 - 0

Simplify:
2x + 2

2x + 2 is your answer

hope this helps
