Q. Given the function y=2+3x32x2 y=\frac{2+3 x}{3-2 x^{2}} , find dydx \frac{d y}{d x} in simplified form.\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Apply Quotient Rule: To find the derivative of the function y=2+3x32x2y=\frac{2+3x}{3-2x^2} with respect to xx, we will use the quotient rule. The quotient rule states that if you have a function that is the quotient of two functions, u(x)v(x)\frac{u(x)}{v(x)}, then its derivative is given by v(x)u(x)u(x)v(x)(v(x))2\frac{v(x) \cdot u'(x) - u(x) \cdot v'(x)}{(v(x))^2}. Here, u(x)=2+3xu(x) = 2 + 3x and v(x)=32x2v(x) = 3 - 2x^2.
  2. Find u(x)u(x) Derivative: First, we need to find the derivative of u(x)=2+3xu(x) = 2 + 3x with respect to xx. The derivative of a constant is 00, and the derivative of 3x3x with respect to xx is 33. Therefore, u(x)=0+3=3u'(x) = 0 + 3 = 3.
  3. Find v(x)v(x) Derivative: Next, we need to find the derivative of v(x)=32x2v(x) = 3 - 2x^2 with respect to xx. The derivative of a constant is 00, and the derivative of 2x2-2x^2 with respect to xx is 4x-4x. Therefore, v(x)=04x=4xv'(x) = 0 - 4x = -4x.
  4. Apply Quotient Rule: Now we apply the quotient rule. We have u(x)=2+3xu(x) = 2 + 3x, v(x)=32x2v(x) = 3 - 2x^2, u(x)=3u'(x) = 3, and v(x)=4xv'(x) = -4x. Plugging these into the quotient rule formula, we get:\newlinedydx=(32x2)3(2+3x)(4x)(32x2)2\frac{dy}{dx} = \frac{(3 - 2x^2) \cdot 3 - (2 + 3x) \cdot (-4x)}{(3 - 2x^2)^2}.
  5. Simplify Numerator: Simplify the expression in the numerator:\newline(32x2)×3(2+3x)×(4x)=96x2+8x+12x2(3 - 2x^2) \times 3 - (2 + 3x) \times (-4x) = 9 - 6x^2 + 8x + 12x^2.
  6. Combine Like Terms: Combine like terms in the numerator:\newline96x2+8x+12x2=9+8x+6x29 - 6x^2 + 8x + 12x^2 = 9 + 8x + 6x^2.
  7. Final Derivative: Now we have the simplified form of the derivative:\newline(dydx=9+8x+6x2(32x2)2)(\frac{dy}{dx} = \frac{9 + 8x + 6x^2}{(3 - 2x^2)^2}).
