To find (dy)/(dx) for the given function, we will use the quotient rule. The function is y = (x^2 + 7x)/(x+2). Let u = x^2 + 7x and v = x+2. Step 1: Find the derivative of u with respect to x. (du)/(dx) = (d)/(dx)(x^2 + 7x) = 2x + 7 Step 2: Find the derivative of v with respect to x. (dv)/(dx) = (d)/(dx)(x+2) = 1 Step 3: Apply the quotient rule, which states that if y = (u)/(v), then (dy)/(dx) = (v du)/(dx) - u (dv)/(dx)v^2. (dy)/(dx) = ((x+2)(2x+7) - (x^2+7x)(1))/((x+2)^2) Step 4: Expand and simplify the numerator. Numerator = (x+2)(2x+7) - (x^2+7x) = (2x^2 + 7x + 4x + 14) - (x^2 + 7x) = 2x^2 + 11x + 14 - x^2 - 7x = (2x^2 - x^2) + (11x - 7x) + 14 = x^2 + 4x + 14 Step 5: Write the final expression for (dy)/(dx). (dy)/(dx) = (x^2 + 4x + 14)/((x+2)^2) Send me the next one 📸
