Question

Using the area model below, write the standard form of the product.-3x2x?5

Answer 1

`(-7x^3+9x^2-3).(-2x^2-5x+6)`

Apply distributive property:

`-7x^3(-2x^2)-7x^3(-5x)-7x^3(6)+9x^2(-2x^2)+9x^2(-5x)+9x^2(6)-3(-2x^2)-3(-5x)-3(6)`
`14x^5+35x^4-42x^3-18x^4-45x^3+54x^2^{}+6x^2+15x-18`

Combine like terms

`14x^5+17x^4-87x^3+60x^2+15x-18`
