Question

Which expression product is modeled by the tiles(2x+1)(x+1)

Answer 1

$(2x + 1)(x + 1)$

•Distribute

$(2x + 1)(x + )$

$2x(x + 1) + 1( x + 1)$

•Distribute

$2x(x + 1) + 1(x + 1)$

$2x² + 2x1(x + 1)$

•Multiply

$2x² + 2x + 1(x + 1)$

$2x² + 2x + x + 1$

•Combine like terms

$2x² + x + x + 1$

$2x²+ 3x + 1$

Solution:

$2x² + 3x + 1$
