If y = (1 + x)^{2}, find (frac{dy}{dx})

A.
x – 1 
B.
2 + 2x 
C.
1 + 2x 
D.
2x – 1
Correct Answer: Option B
Explanation
If y = (1 + x)^{2}, find (frac{dy}{dx})
y = (1 + x)^{2}
(frac{dy}{dx}) = 2(1 + x)
= 2 + 2x
If y = (1 + x)^{2}, find (frac{dy}{dx})
y = (1 + x)^{2}
(frac{dy}{dx}) = 2(1 + x)
= 2 + 2x
