21-7y+3x-xy
If: 31 is the highest common factor of 155 and 217 Then: 155x+217y = 31 Divide all terms by 31: 5x+7y = 1 So: 5*1/10 + 7*1/14 = 1 because 1/2 + 1/2 = 1 Therefore the possible values of x and y are 1/10 and 1/14 respectively Check: (155*1/10)+(217*1/14) = 31

The other factor is 1.
(a + 2b)(a + 2b)
factor the trinomial 16x^2+24x+9
You can't factor it
That does not factor neatly.
Factor x2 plus 12xp plus 36p2 is (x+6p)(x+6p).

No
Not factorable
The only factor is 2. 2*(t3 + 2t2 + 4x)
