1) y ' = ( u'v - uv') / v²
u =( 6-2x)³ u' = 3.(-2)(6-2x)²
v = 2x+3 v' = 2
y ' = [-6(6-2x)²(2x+3) - 2( 6-2x)³ ] / (2x+3)² [ (6-2x)² dikeluarkan / difaktorkan ]
y' = (6-2x)²[-12x-18-2(6-2x)] / (2x+3)² = (6-2x)² [ -12x - 18-12+4x] /(2x+3)²
y ' = (6-2x)² [ - 8x - 30] /(2x+3)² = (36-24x+4x²)(-8x-30) / (4x²+12x+9)
jawaban sampe disinipun sdh benar/cukup tidak perlu dijabarkan lagi tp kalo mau jg ngak apa2
2) y = √4-3x
y' = 1/2 ( -3) (4-3x)^(-1/2) [ pangkat minus setengah]
y'= -3/2 1/√4-3x . (√4-3x / √4-3x) [ dikali akar sekawan/ dirasionalkan]
y' = [(-3/2) √4-3x ]/( 4-3x) atau y ' = -3√4-3x /(8-6x)
