Question

Bantuan nya ka tolong yah

Answer 1

Misal
U = (x^2 - 3)^3
U'= 3(x^2 - 3)^2.2x
U'= 6x.(x^2 - 3)^2

V = 5x^2
V'= 5.2.x
V'= 10x

y' = (U'. V - U.V') /V^2
y'= ((6x.(x^2 - 3)^2).5x^2 - ((x^2 - 3)^3).10x) /(5x^2)^2
y'= (30x^3.(x^2 - 3) - 10x(x^2 - 3)^3)/25x^4
y'= (10x(x^2 - 3)(3x^2 - (x^2 - 3)^2)/25x^4
