Tolong bantuanya tentukan turunan fx:5(2x²+4x)danfx:(2x+3)(5x+4)

Penjelasan dengan langkah-langkah:

$f(x) = 5(2 {x}^{2} + 4x) \ = 10 {x}^{2} + 20x$

f'(x) = 10(2)x +20 = 20x +20

atau

f'(x) = 20(x+1)

$f(x) = (2x + 3)(5x + 4) \ = 10 {x}^{2} + 8x + 15x + 12 \ = 10 {x}^{2} + 23x + 12$

f'(x) = 10(2x) + 23 = 20x + 23
