sorry i am not sure but i dont think it has an answer If this equation is: x^2 - 36 = 5x, then: x^2 - 36 = 5x subtract 5x to both sides; x^2 - 5x - 36 = 0 Factor; (x + 4)(x - 9) = 0 x + 4 = 0 or x - 9 = 0 x = -4 or x = 9
(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)
When factored it is: (x-9)(x+4)
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
x2-5x-36 = (x-9(x+4) when factored
x = 1
5x-x=36 4x=36 x=36/4 x=9
5x - 11 - 36 is a math equation. 5x - 11 -36 can be simplified to read 5x- 47. I suspect that there is an equals missing, ie the question was/should be: "Solve for x in 5x - 11 equals -36" 5x - 11 = -36 → 5x = -25 → x = -5
5x + 36 = x Subtract x from both sides: 4x + 36 = 0 Subtract 36 from both sides: 4x = -36 Divide both sides by 4: x = -9
It is (x - 9)*(x + 4)
It is: (x-4)(x+9)
