(2x - 9)(2x - 9) or (2x - 9)2
66x^3 - 36x^2 = 6x^2(11x - 6) 55x - 30 = 5(11x - 6) 66x^3 - 36x^2 + 55x - 30 = (6x^2 + 5)(11x - 6)
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
10x2-36x+18 Divide all terms by 2: 5x2-18x+9 = (5x-3)(x-3) when factored
The LCM of 12, 16, 24, and 36 is: 144
x2+36x+120 (x+6)(x+20)
3x2 + 36x + 81 = 3(x2 + 13x + 27)
16 + x = 36x = 36 - 16 = 2016 + 20 = 36
4x2-36x+81 (2x-9)(2x-9)
52x - 7 = 33 - 36x + 4 52x + 36x = 33 + 7 + 4 88x = 44 x = 1/2
4x + 32x + 9 = 36x + 9
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
(3X + 9) (X + 9)
(x - 6)(5x - 6)
3x2 + 36x + 81 = 3(x2 + 12x + 27) = 3(x + 3)(x + 9), which are its prime factors; or, if you prefer, 3x2 + 36x + 81 = (3x + 9)(x + 9), which is also accurate. You may easily verify these results by multiplying back.
(7x2 + 9)(4x - 1)
42% of 36x = 36x*42/100 = 15.12x%
