A) Quantity A is greater. B) Quantity B is greater. C) The two quantities are equal. D) The relationship cannot be determined from the information given.

Doing computations we get quantity A equal to 4x^4-4x^2+3x^3-3x and quantity B equal to 4x^4+4x^2+3x^3+3x. Now, simplifying we get A equal to -4x and B equal to 3. Then, whatever x between 0 and 1, B is greater!

a short cut: extract one x from (x^3-x) we get x(x^2-1)(4x+3) on the left. extract one x from (4x^2+3x) we get x(x^2+1)(4x+3) on the right. x(4x+3) canceled out. (x^2-1)<(x^2+1)

correct: A (maybe includes miscalculatings!) (x^3 - x)(4x + 3) = 4x^4 + 3x^3 - 4x^2 -3x

(x^2 + 1)(4x^2 + 3x) = 4x^4 + 3x^3 + 4x^2 + 3x

We compare these two and simplify as much as possible. 4x^4 + 3x^3 - 4x^2 -3x vs 4x^4 + 3x^3 + 4x^2 + 3x Omitting 4x^4 + 3x^3: - 4x^2 -3x vs 4x^2 + 3x -(4x^2 + 3x) vs (4x^2 + 3x) a) When 4x^2 + 3x is negative then the value in the left will be positive when multiplied by it’s negative sign. And the right value will be negative and thus less. 4x^2 + 3x < 0 —> 4x^2 < -3x —> x < -3/4 b) When 4x^2 + 3x is positive the value in the right will be bigger. 4x^2 + 3x > 0 —> 4x^2 > -3x —> x > -3/4

BUT it's mentioned that x is between 0 and 1 and it will be case b. so A is bigger than B
