Here is how you solve this problem... 5x*4-3x*5*2x-9= (Combine like-terms) 5x-3x*2x= 2x*2x=(2x)2 (Add the rest of the problem) (2x)2*4*5-9=(2x)2*20-9 (2x)2*11 (2x)2 *11= your answer
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
3x2-2x-2 = (3x-3.645751311)(x+0.5485837704) when factored with the help of the quadratic equation formula
If you mean: -3x-5x+1+8x-2x-9 then the result is -2x-8
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3

3x-2 and 2x-9, now for this it kind of depends on how the equation is set out if it set out likw this 3x-2+2x-9 then you would answer it like this: -6x+-18x= 12x
3x+9=2x+10 3x+9-2x=10 9+x=10 x=1
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
2(x+5) =3X+1 => 2x+10-3x-1=0. => -x+9 => x=9
Integrate by parts: ∫ uv dx = u ∫ v dx - ∫ (u' ∫ v dx) dx Let u = -2x Let v = cos 3x → u' = d/dx -2x = -2 → ∫ -2x cos 3x dx = -2x ∫ cos 3x dx - ∫ (-2 ∫ cos 3x dx) dx = -2x/3 sin 3x - ∫ -2/3 sin 3x dx = -2x/3 sin 3x - 2/9 cos 3x + c
y=-2/3x
(2x x 3x) x 2 = 12x (2x times 3x times 2)
5
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
