It is: x = 5/3 and x = -3
They are: x = 5/3 and x = -3
x = 0 or x = 2
3x2-4x-15 = 0 (3x+5)(x-3) = 0 x = -5/3 or x = 3
the empty set.
No.
(0, -14)
Solution: x = 1/4 and x = -3.
The solution: x = 6/7 and x = -1
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
{-1,7}
6x = 1 x = 1/6
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
