Hey mate, here is your answer -:)

---------------------------------------------------

$= \frac{2.3 \times 2.3 - 0.3 \times 0.3}{2.3 \times 2.3 - 2 \times 2.3 \times 0.3 + 0.3 \times 0.3} \\ \\ = \frac{5.29 - 0.09}{5.29 - 1.38 + 0.09} \\ \\ = \frac{5.2}{5.38 - 1.38} \\ \\ = \frac{5.2}{4} \\ \\ = 1.3$
