7x2 -4x -5x2 +2x = 2x2 -2x
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
-x2+2x
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
7x2 -4x -5x2 +2x = 2x2 -2x
The discriminant is 121.
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
5x-4x = 1
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
If the equation is 4x squared - 5x + 10 = 0, then you set a = 4, b = -5, c = 10. Replace these numbers in the quadratic formula.
5x - 4x = x
Well, darling, the Least Common Multiple (LCM) of 4x and 5x is simply 20x. You see, 4x and 5x are both factors of 20x, making it the smallest multiple they both share. So, there you have it, sweet pea, 20x is the LCM of those two little troublemakers.
