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`
