Question

Write -2x^2 ( -5x^2 + 4x^3 ) in Standard Form.

Answer 1

-2x^2=-4x.

(-5x^2+4x^3)=(-25x+64x).

-4x(-25x+64x)=100x-256x.

100x-256x=-156x

-156x is your final answer.

Answer 2

- 8
`x^(5)` + 10
`x^(4)`

distribute the parenthesis by - 2x²

= 10
`x^(4)` - 8
`x^(5)`

= - 8
`x^(5)` + 10
`x^(4)` ← in standard form

Note that a polynomial expressed in standard form

The first term is the term with the highest exponent followed by the other terms in descending order of exponents
