Question

please give me answer ​

Answer 1

Answer:

60$x^{2}$+20x+16

Step-by-step explanation: first multiply both the brackets then we get,

20$x^{3}$+16x+10$x^{2}$+8

now differentiate with respect to x then

$\frac{d}{dx}$(20$x^{3}$+16x+10$x^{2}$+8)=3(20$x^{2}$)+16(1)+2(10x)+0

                                 = 60$x^{2}$+16+20x
