Question 16 • Algebra 2 with Probability
A quadratic-in-form equation can be rewritten as a quadratic equation using a substitution. In choice A, let u = x²; then 6x⁴ + 7x² − 3 = 0 becomes 6u² + 7u − 3 = 0, which is quadratic in u. The other choices do not have exponents that fit this quadratic pattern.
