[tex] \frac{5}{24} \times 1.2 + {1.4}^{2} = \frac{5}{24} \times \frac{12}{10} + {( \frac{14}{10} )}^{2} = \frac{1}{2} \times \frac{1}{2} + \frac{14 \times 14}{10 \times 10} = \frac{1}{4} + \frac{7 \times 7}{5 \times 5} = \frac{1}{4} + \frac{49}{25} = \frac{25}{100} + \frac{196}{100} = \frac{221}{100} = 2.21[/tex]
