Question

d/DX[2x² +5x+2] solve this ​

Answer 1

Question

• $\frac{d}{dx} (2 {x}^{2} + 5x + 2)$= ?

Answer:-

• The right ans of the of question is 4x+5

Solution:-

$= > \frac{d}{dx} ( 2{x}^{2} + 5x + 2) \\ = > \frac{d}{dx} (2 {x}^{2} ) + \frac{d}{dx} (5x) + \frac{d}{dx} (2) \\ = > 2 \frac{d}{dx} ( {x}^{2} ) + 5 \frac{d}{dx} (x) + \frac{d}{dx} (2) \\ = > 2 \times 2x + 5 \times 1 + 0 \\ = > 4x + 5$

Used formula:-

1) $\frac{d}{dx} ( {x}^{n} ) = n \times {x}^{n - 1}$

2)$\frac{d}{dx} (constant) = 0$
