-x2+2x

x2 + x2 = 2x2 2x^2

2x2 + x2 = 3x2

If: 2x+y = 5 and x2-y2 = 3 Then the solutions work out as: (2, 1) and ( 14/3, -13/3)

Factor it out: (x+2) squared

x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2

x2

x2/2x = x2-1/2 = x/2

x2+2x-120 = (x+12)(x-10) when factored

If you mean: x2+2x+1 = 0 then it is a quadratiic equations whose solutions are equal because x = -1 and x = -1

2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2

If: x2+2x-3 = 0 Then: x = 1 or x = -3

x2 - 2x = x(x-2)

None because the discriminant is less than zero

((15xy2)/(x2+5x+6))/((5x2y)/(2x2+7x+3)) =(15xy2/5x2y)*(2x2+7x+3)/(x2+5x+6) =(3y/x)*(((2x+1)(x+3))/((x+2)(x+3) =(3y(2x+1))/(x(x+2)) =(6xy+3y)/(x2+2x)

x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3

2/x + 1/x2 = (2x+1)/x2

x2+2x is a Mathematical expression. Its factors are x and x+2.

-x2 + 2x + 48 = (-x - 6)(x - 8)

(2x3 - x2) = x2 (2x - 1)

x2 - 2x = x(x - 2)

2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5

x3 - x2 + 2x = x*(x2 - x + 2) which cannot be factored further.
