The expression is likely 4x2 - 36x +81
which is the same as (2x - 9)(2x - 9) or (2x - 9)2
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
4x2-36x+81 (2x-9)(2x-9)
x = sq root of 36x = 6x = -6
(3X + 9) (X + 9)
(2x - 9)(2x - 9)
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
4x2-36x+81 (2x-9)(2x-9)
x = sq root of 36x = 6x = -6
(x - 6)(5x - 6)
(3X + 9) (X + 9)
52x - 7 = 33 - 36x + 4 52x + 36x = 33 + 7 + 4 88x = 44 x = 1/2
(7x2 + 9)(4x - 1)
(2x - 9)(2x - 9)
x + 36 = 82x = 82 - 36x = 46
Greatest common factor of 16x and 36x is 4x.
I'm guessing that's 36x^2 - 36x + 9 which factors to 9(2x - 1)(2x - 1)
16 + x = 36x = 36 - 16 = 2016 + 20 = 36
