$3\frac{d}{dx}\left(x\right)\left(x^2-1\right)+\left(3x+2\right)\frac{d}{dx}\left(x^2\right)$

The derivative of the linear function is equal to $1$

$3\cdot 1\left(x^2-1\right)$

Any expression multiplied by $1$ is equal to itself

$3\left(x^2-1\right)$
11

The derivative of the linear function is equal to $1$

$3\left(x^2-1\right)+\left(3x+2\right)\frac{d}{dx}\left(x^2\right)$

The power rule for differentiation states that if $n$ is a real number and $f(x) = x^n$, then $f'(x) = nx^{n-1}$

$2\left(3x+2\right)x^{\left(2-1\right)}$

Subtract the values $2$ and $-1$

$2\left(3x+2\right)x$
12

The power rule for differentiation states that if $n$ is a real number and $f(x) = x^n$, then $f'(x) = nx^{n-1}$

$3\left(x^2-1\right)+2\left(3x+2\right)x$

Multiply the single term $3$ by each term of the polynomial $\left(x^2-1\right)$

$3x^2-1\cdot 3+2\left(3x+2\right)x$

Multiply $-1$ times $3$

$3x^2-3+2\left(3x+2\right)x$

Solve the product $2\left(3x+2\right)x$

$3x^2-3+\left(6x+4\right)x$

Multiply the single term $x$ by each term of the polynomial $\left(6x+4\right)$

$3x^2-3+6x\cdot x+4x$

When multiplying two powers that have the same base ($x$), you can add the exponents

Combining like terms $3x^2$ and $6x^2$

$9x^2-3+4x$
13

Simplify the derivative

$9x^2-3+4x$

$9x^2-3+4x$
