Question

Is this the right answer?

Answer 1

Hello!

Number 2 and 4 is wrong, other than that everything else is all good.

`2)`
`6x^4 - 12x^5 + 90x^1^(3)`

The Greatest common factor is 6x^4.

The GCF needs to have the smallest exponent from the variables.

The correct answer should be 6x^4 ( 1 - 2x + 15x^9)

`4)`
`x^2 - 36`

x (x - 36) is wrong because if we use the distributive property, the answer would be x^2 - 36x. Notice that there shouldn't be a variable multiplying 36.

The correct answer would be (x - 6)(x + 6)

x^2 + 6x - 6x - 36

x^2 - 36.

Hope this helps!
