(x + 2)(x + 1)
x = plus or minus 6.
x2 + 8xy + 15y2 = (x + 3y) (x + 5y)
x(x2+5x+6)
3(x + 4)(x + 1)
(x + 12)(x - 3)
x sq equalls 36 and x equalls plus or minus 6
(6x - 1)(6x - 1)
9x2 + 27x - 36 = 9(x2 + 3x - 4) = 9(x + 4)(x - 1)
3x2-21x+36 =3(x2-7x+12) =3(x-4)(x-3)
(a + x^2)(b + y^2)
No
Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
