Answer:
2/3
Step-by-step explanation:
Your −3x + 3 −1 is not an equation and thus has no solution.
If, on the other hand, you meant
−3x + 3 = 1
then -3x = -2, and x = 2/3
Value of a = 3
Value of a + b = 3 + (-2/3)
Value of a + b = 2 1/3
Difference = 3 - 2 1/3
Difference = 2/3

Answer: They are 2/3 unit apart

To factor a quadratic equation that has a leading coefficient, multiply the most and least significant coefficients together. In this case 6 * -4 = -24
We need to find two numbers that multiply to -24 and add to -5. We will split the middle term into these two numbers.
6x^2 -8x + 3x - 4 = 0
Here you can see that we split -5x into -8x and 3x.
Now we can factor by grouping. To do this, group the first two terms together and the last two terms together. Factor out whatever you can.
(6x^2 - 8x) + (3x - 4)
2x(3x - 4) + 1(3x - 4)
Notice that the second group had nothing to factor out so we just pull out a 1. Now we can rearrange the factored form according to the distributive property.
(2x+1)(3x-4) = 0
So the solutions are x = -1/2 and x = 4/3
