solve for x: by completing the square:

(3 x^2 - 4 x + 2)/(3 x - 19) = 0

Multiply both sides by 3 x - 19:

3 x^2 - 4 x + 2 = 0

Divide both sides by 3:

x^2 - (4 x)/3 + 2/3 = 0

Subtract 2/3 from both sides:

x^2 - (4 x)/3 = -2/3

Add 4/9 to both sides:

x^2 - (4 x)/3 + 4/9 = -2/9

Write the left hand side as a square:

(x - 2/3)^2 = -2/9

Take the square root of both sides:

x - 2/3 = (i sqrt(2))/3 or x - 2/3 = -(i sqrt(2))/3

Add 2/3 to both sides:

x = 2/3 + (i sqrt(2))/3 or x - 2/3 = -(i sqrt(2))/3

Add 2/3 to both sides:

Answer: x = 2/3 + (i sqrt(2))/3 or x = 2/3 - (i sqrt(2))/3

Why is division not commutative
Kamila [148]
Division CANNOT be commutative, here is why

lets say the problem is 24÷4

it is obviously  6

but when you flip 24÷4, you get 4÷24

and... 4÷24 is 0.16666666

6 and 0.1666 is totally different :p

Answer:

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12. A positive integer greater than 1, or an algebraic expression, that has only two factors (i.e., itself and 1) is termed prime; a positive integer or an algebraic expression that has more than two factors is termed composite. The prime factors of a number or an algebraic expression are those factors which are prime. By the fundamental theorem of arithmetic, except for the order in which the prime factors are written, every whole number larger than 1 can be uniquely expressed as the product of its prime factors; for example, 60 can be written as the product 2·2·3·5.
