How do you differentiate #x^2 + 8x + 3 / sqrtx# using the quotient rule?

Explanation:
The quotient rule is not required here as we have a sum of terms which can be differentiated using the
#color(blue)" power rule"#
#d/dx(ax^n)=nax^(n-1)# Before applying this rule we need to rewrite the term
#3/sqrtx#
#rArr3/sqrtx=3/x^(1/2)=3x^(-1/2)# We now have:
#x^2+8x+3x^(-1/2)#
#=2x+8-3/(2x^(3/2))#
