Solve x*4^2/3x-6

$$\frac { x \times 4 ^ { 2 } } { 3 x - 6 }$$

Differentiate w.r.t. x

$$-\frac{32}{3\left(x-2\right)^{2}}$$

Steps Using Derivative Rule for Quotient

Calculate 4 to the power of 2 and get 16.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{x\times 16}{3x-6})$$

For any two differentiable functions, the derivative of the quotient of two functions is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the denominator squared.

$$\frac{\left(3x^{1}-6\right)\frac{\mathrm{d}}{\mathrm{d}x}(16x^{1})-16x^{1}\frac{\mathrm{d}}{\mathrm{d}x}(3x^{1}-6)}{\left(3x^{1}-6\right)^{2}}$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$\frac{\left(3x^{1}-6\right)\times 16x^{1-1}-16x^{1}\times 3x^{1-1}}{\left(3x^{1}-6\right)^{2}}$$

Do the arithmetic.

$$\frac{\left(3x^{1}-6\right)\times 16x^{0}-16x^{1}\times 3x^{0}}{\left(3x^{1}-6\right)^{2}}$$

Expand using distributive property.

$$\frac{3x^{1}\times 16x^{0}-6\times 16x^{0}-16x^{1}\times 3x^{0}}{\left(3x^{1}-6\right)^{2}}$$

To multiply powers of the same base, add their exponents.

$$\frac{3\times 16x^{1}-6\times 16x^{0}-16\times 3x^{1}}{\left(3x^{1}-6\right)^{2}}$$

Do the arithmetic.

$$\frac{48x^{1}-96x^{0}-48x^{1}}{\left(3x^{1}-6\right)^{2}}$$

Combine like terms.

$$\frac{\left(48-48\right)x^{1}-96x^{0}}{\left(3x^{1}-6\right)^{2}}$$

Subtract 48 from 48.

$$\frac{-96x^{0}}{\left(3x^{1}-6\right)^{2}}$$

For any term t, t^{1}=t.

$$\frac{-96x^{0}}{\left(3x-6\right)^{2}}$$

For any term t except 0, t^{0}=1.

$$\frac{-96}{\left(3x-6\right)^{2}}$$

Evaluate

$$\frac{16x}{3\left(x-2\right)}$$

Short Solution Steps
