3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
5x-2x-3x+4x = (5-2-3+4)x = 4x
3x - 8 = 5x + 2 <+8 and - 5x off each side> -2x = 10 <divide each side by -2x> x = -5
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
The answer to the equation 5x - 3x + 2 = 1 is -0.5.
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x

3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
3x+2 = 5x so 2x = 2 and hence x = 2/2 = 1
(3x - 5x) + (x2 - 6x2) = -2x -5x2 = -x(2 + 5x)
2(3x + 4) + 5x - 2
