Option 1: MBXZIZH
Option 2: OCXALAI
Option 3: NCYAMAI
Option 4: NBYZMZI

Question : If $16 y^2-k=\left(4 y+\frac{3}{2}\right)\left(4 y-\frac{3}{2}\right)$, then the value of $k$ is:
Option 1: $\frac{9}{4}$
Option 2: $\frac{11}{4}$
Option 3: $\frac{6}{4}$
Option 4: $\frac{7}{4}$
Correct Answer: $\frac{9}{4}$
Solution : $16 y^2-k=\left(4 y+\frac{3}{2}\right)\left(4 y-\frac{3}{2}\right)$ $⇒(4y)^2-k=(4y)^2-(\frac{3}{2})^2$ $⇒k=(\frac{3}{2})^2$ $\therefore k = \frac{9}{4}$ Hence, the correct answer is $\frac{9}{4}$.
