factor the trinomial 16x^2+24x+9
(m + 9)(m + 9)
(2m + 1)(8m + 9)
(x+1)(x+9)
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)
18b+9=9(b+2)
4x3+12x2+3x+9
(3X + 9) (X + 9)
(x+1)(x+9)
12Y + 9 all I can see to factor out is 3 3(4Y + 3)
18b+9 = 9(b+2)
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
