(2x+3)(x+3)
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
9x/2x = 9/2 = 4.5
9x2 - 18x + 99(x2 - 2x + 1)==========
2x2+9x+9 = (2x+3)(x+3) when factored
2x+3=9x 3=9x-2x 3=7x x=3/7
2x + 3= 9.X=
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
[9x-5x+1] + [16x-2x-9] [4x+1] + [14x-9] [18x2+8]
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
