Answer 1

a) 51 + 18x

= 3(17 + 6x).

b) 43x - 8y + 2 - 24x + x - 9

= 19x - 8y - 7 - x.

c) 2√5a - 3•10√2b - 3•5√5b + 10√7a

= 2√5a - 30√2b - 15√5b + 10√7a.

d) 13√13x + 10 + 3•2√13x - 7 - 2•4√13x

13√13x + 10 + 6√13x - 7 - 8√13x

= 11√13x + 3.

e) 3x^2 + 6 + 5x - 9x^2 - 4x - 12

-6x^2 - 6 + x

= -6x^2 + x - 6.

f) 14x^2 + 7 - 27x^3 - 6x - 15

14x^2 - 8 - 27x^3 - 6x

= -27x^3 + 14x^2 - 6x - 8.
