Simplify x(2x^2+1)

$x (2 x^{2} + 1)$

Step 1

Apply the distributive property.

$x (2 x^{2}) + x \cdot 1$

Step 2

Simplify the expression.

Rewrite using the commutative property of multiplication.

$2 x \cdot x^{2} + x \cdot 1$

Multiply $x$ by $1$ .

$2 x \cdot x^{2} + x$

Step 3

Multiply $x$ by $x^{2}$ by adding the exponents.

Move $x^{2}$ .

$2 (x^{2} x) + x$

Multiply $x^{2}$ by $x$ .

Raise $x$ to the power of $1$ .

$2 (x^{2} x^{1}) + x$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$2 x^{2 + 1} + x$

Add $2$ and $1$ .

$2 x^{3} + x$
