Q. Given the function y=3x+26+x2, find dxdy in simplified form.Answer: dxdy=
Identify Function: Identify the function to differentiate.We are given the function y=3x+26+x2. We need to find the derivative of this function with respect to x, which is denoted as dxdy.
Apply Quotient Rule: Apply the quotient rule for differentiation.The quotient rule states that the derivative of a function in the form of v(x)u(x) is given by (v(x))2v(x)⋅u′(x)−u(x)⋅v′(x). Here, u(x)=6+x2 and v(x)=3x+2.
Differentiate u(x) and v(x): Differentiate u(x) and v(x) with respect to x. The derivative of u(x)=6+x2 with respect to x is u′(x)=0+2x. The derivative of v(x)=3x+2 with respect to x is v(x)0.
Apply Derivatives to Quotient Rule: Apply the derivatives found in Step 3 to the quotient rule. dxdy=(3x+2)2(3x+2)⋅(2x)−(6+x2)⋅(3)
Simplify Expression: Simplify the expression.(dxdy)=(9x2+12x+4)(6x2+4x−18−3x2)(dxdy)=(9x2+12x+4)(3x2+4x−18)
Check for Factorization: Check for any possible simplification or factorization. The numerator and the denominator do not have any common factors, so the expression is already in its simplest form.
