Answer 2

Okay, first let us expand it by doing the indicated multiplication...

-10+2√5-15√5+15 combining like terms we have:

2√5-15√5+5  notice that the constant 5 can be expressed as √5√5 so you have:

2√5-15√5+√5√5  since these all have the same √5 coefficient we can say:

(2-15+√5)√5

(√5-13)√5

5-13√5
