Question

using tiles to multiply a monomial by a binomial
what is the product of $x(x + 1)$?
$\circ$ $2x + x$
$\circ$ $x^2 + 2x$
$\circ$ $2x^2 + x$
$\circ$ $x^2 + x$

Explanation:

Step1: Apply distributive property

$x(x + 1) = x \cdot x + x \cdot 1$

Step2: Simplify each term

$x \cdot x = x^2$, $x \cdot 1 = x$

Step3: Combine simplified terms

$x^2 + x$

Answer:

D. $x^2 + x$
