(3x2)+5=11
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
__x2_-_x______________ 2x - 1 ) 2x3 - 3x2 + x + 5 2x3 - x2 --------- -2x2 + x -2x2 + x ------------ 0 + 5 = 5 So the answer is x2 - x with remainder of 5. Couldn't get it to format correctly, but hopefully you can read it to understand the work.
3x-5=3x+5 There is no solution.
9x2 + 30x + 25
(x + 1) / (2x3 + 3x + 5) --- Can't depict long division here, but you can work this out by seeing if (x + 1) is a factor of (2x3 + 3x + 5). If it is, then the answer will be 1/(the other factor). In this case, that is true. (2x3 + 3x + 5)/(x + 1) = 2x2 - 2x + 5, so the term term above is equal to: 1 / (2x2 - 2x + 5)
2x**3-10x**2+3x-15 2x**2(x-5)+3(x-5) (2x**2+3)(x-5)
(x3 - 3x2 + 4x - 7) - (2x3 + x2 - 3x - 5)
(3x2)+5=11
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
It is equivalent to: 3x+6+5 = 3x+11
__x2_-_x______________ 2x - 1 ) 2x3 - 3x2 + x + 5 2x3 - x2 --------- -2x2 + x -2x2 + x ------------ 0 + 5 = 5 So the answer is x2 - x with remainder of 5. Couldn't get it to format correctly, but hopefully you can read it to understand the work.
3x-5=3x+5 There is no solution.
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
9x2 + 30x + 25
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
