-x2 + 2x + 48 = (-x - 6)(x - 8)
17
The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.
((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)
2/x + 1/x2 = (2x+1)/x2
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
x= -3
x2 + 2x - 15 = (x - 3)(x + 5)
x2 + 2x - 15 = (x + 5)(x - 3)
3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
(x2 + 2x + 15)/(x - 3) = x + 5 + 30/(x - 3) where x ≠3
x2+2x-15 = (x+5)(x-3) when factored
3(x2 - 2x + 3)
(x - 1)(x + 3)
-2x3 + 2x2 + 12x = -2x(x2 - x - 6) = -2x(x2 + 2x - 3x - 6) = -2x[ x(x + 2) - 3(x + 2) ] = -2x(x - 3)(x + 2)
It is at: (-1, 0)
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
