Question

Help !!!!!!!!!! How can I Select the expressions that are factored correctly.

Answer 1

`3x^2 + 14x + 8 = (3x+2)(x+4)`

`x^2-10x+25=(x-5)^2`

Explanation:

`x^2 - 26 = (x-6)^2`

`(x-6)(x-6)`

`x^2-6x-6x+36`

`x^2-12x+36` (wrong)

`3x^2 + 14x + 8 = (3x+2)(x+4)`

`(3x+2)(x+4)`

`3x^2+12x+2x+8`

`3x^2+14x+8` (true)

`x^2-7x+10=(x+5)(x+2)`

`(x+5)(x+2)`

`x^2+2x+5x+10`

`x^2+7x+10` (wrong)

`x^2-10x+25=(x-5)^2`

`(x-5)^2`

`(x-5)(x-5)`

`x^2-5x-5x+25`

`x^2-10x+25` (true)

Hope this helps!
