CPM Homework Help : CC1 Problem 6-107

Sketch the collection of algebra tiles that is described by the following expression. Rewrite the area of the collection by combining like terms.

$7x+2x^2+3x^2+3+x$

Hint:

Indicate how many $x^2$ , $x$ , and unit tiles are needed. Start by finding out how many total $x$ -tiles are needed.

More Help 1:

Circle any term that has only one $x$ in it.
Then add the coefficients.
$\enclose{circle}[mathcolor="orange"]{\color{black}{7x}} +2x^2+3x^2+3+\enclose{circle}[mathcolor="orange"]{\color{black}{x}}$
Note: A variable without a coefficient showing actually has a coefficient of $1$ .

More Help 2:

Now do the same to find the number of $x^2$ tiles. How many unit tiles are needed?
