Complete the mixed number equation that is represented by the area model

From the given data, it is clear that the first area model represents the fraction

From the second area model,

Total number of regions = 6

Number of shaded regions = 2

The fraction represented by the model =

Let's complete the expression.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

answer: the is put the 450

step-by-step explanation:
