उत्तर
Here, we will use the identity \[\left( x + a \right)\left( x + b \right) = x^2 + \left( a + b \right)x + ab\].
\[\left( z + \frac{3}{4} \right)\left( z + \frac{4}{3} \right)\]
\[ = z^2 + \left( \frac{3}{4} + \frac{4}{3} \right)x + \frac{3}{4} \times \frac{4}{3}\]
\[ = z^2 + \frac{25}{12}z + 1\]
