How to solve a + 2a * 1

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

$3$

Steps Using Definition of a Derivative

Multiply $2$ and $1$ to get $2$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a+2a)$$

Combine $a$ and $2a$ to get $3a$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(3a)$$

The derivative of $ax^{n}$ is $nax^{n-1}$.

$$3a^{1-1}$$

Subtract $1$ from $1$.

$$3a^{0}$$

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

$$3\times 1$$

For any term $t$, $t\times 1=t$ and $1t=t$.

$$3$$
