Question

Could someone help me with this ASAP? thanks !

Answer 1

A.
`6x^2`+-5x+14x+-35

`6x^2`+9x-35

B.
`5x^4+-3x^3+10x^3+-6x^2`

`5x^4+7x^3-6x^2`

C.
`25x^2+-20x+20x+-16`

`25x^2-16`

D.
`x^4+-4x^2+-7x^2+28`

`x^4-11x^2+28`

`====================================`

Explanation:

A. (3x*2x)+(3x*-5)+(7*2x)+(7*-5)

Multiply and simplify.

`6x^2`+9x-35

B. (
`x^2*5x^2`)+(
`x^2*`-3x)+(2x
`*5x^2`)+(2x
`*-3x`)

Multiply and simplify.

`5x^4+7x^3-6x^2`

C.
`(5x*5x)+(5x*-4)+(4*5x)+(4*-4)`

Multiply and simplify.

`25x^2-16`

D.
`(x^2*x^2)+(x^2*-4)+(-7*x^2)+(-7*-4)`

Multiply and simplify.

`x^4-11x^2+28`

I hope this helps!

But you should really do this yourself.
