 Differentiate with respect to x by using suitable method :
[ Bezakan terhadap x dengan menggunakan kaedah yang sesuai : ]
 $y=\left(5x^2-9\right)\left(x^3-1\right)$  

•  $\left(x^3-1\right)\left(10x\right)+\left(5x^2-9\right)\left(3x^2\right)$  

•  $\left(x^3-1\right)\left(3x^2\right)+\left(5x^2-9\right)\left(10x\right)$  

Differentiate with respect to x by using suitable method :
[ Bezakan terhadap x dengan menggunakan kaedah yang sesuai : ]
 $y=\frac{3x^5}{\left(x^2+1\right)}$  

•  $\frac{\left(x^2+1\right)\left(2x\right)-\left(3x^5\right)\left(15x^4\right)}{\left(x^2+1\right)^2}$  

•  $\frac{\left(x^2+1\right)\left(15x^4\right)-\left(3x^5\right)\left(2x\right)}{\left(x^2+1\right)^2}$
