Move all terms to one side
4x^2 - 3 - 11x = 0
Split the second term in 4x^2 - 3 - 11x into two terms
4x^2 + x - 12x - 3 = 0
Factor out common terms in the first two terms, then in the last two terms
x(4x + 1) -3(4x + 1) = 0
Factor out the common term 4x + 1
(4x + 1)(x - 3) = 0
Solve for x
x = -1/4, 3
Answer: C. {-1/4, 3}
