Compute it:
- Let x = 2/11. Then the expression is 33x^2 − 28x = x(33x − 28).
- 33x = 33*(2/11) = 6, so 33x − 28 = 6 − 28 = -22.
- Value = x * (-22) = (2/11) * (-22) = -4.
If you do it as fractions:
- 33*(2/11)^2 = 33*(4/121) = 132/121
- 28*(2/11) = 56/11 = 616/121
- 132/121 − 616/121 = -484/121 = -4
Answer: -4
