Question

Find: d÷dx:(3x²+4x)​

Answer 1

Explanation:

let y = 3x² + 4x

D . w . r . to . x

dy/dx = d/dx (3x² + 4x)

= 6x + 4

Answer 2

Answer:

d/dx (3x² + 4x) = 6x +4.

Explanation:

Remember this result to proceed forward,

d/dx (x^n) = n (x)^n-1.

Required: d/dx (3x² + 4x)

=d/dx (3x²) + d/dx (4x)

=3 d/dx(x²) + 4 d/dx(x)

=6x+4 (∵d/dx (x²)=2x and d/dx (x)=1).
