It is an algebraic expression that can be simplified to: 45x -16
(9x)2 +9x/(45x)2 +81= 9+9x/86
45x
(5x+4)(9x+9) FOIL First (5x*9x=45x**2) Outside (5x*9=45x) Inside (4*9x=36x) Last (4*9=36) 45x**2+45x+36x+36 45x**2+81x+36 9(5x**2+9x+4x)
The answer is 1324. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.

3x3 - 24x2 + 45x = 3x*(x2 - 8x + 15) = 3x*(x - 3)*(x - 5)
88x+33=45x*56 88x+33=2520x 33=2432x x=0.013569
x(x + 9)(x + 5)
3x(x - 5)(x - 3)
If: -45x-6 = 2 Then: -45x = 2+6 => -45x = 8 And: x = -8/45
