simplify

- 12.5 + \frac{1}{2} (- 9.8) (1.5)^{2}

- \frac{941}{40}

Solution steps

- 12.5 + \frac{1}{2} (- 9.8) \cdot 1. 5^{2}

12.5 = \frac{25}{2}

= - \frac{25}{2} + \frac{1}{2} (- 9.8) \cdot 1. 5^{2}

= - \frac{25}{2} + \frac{1}{2} (- \frac{49}{5}) \cdot 1. 5^{2}

\frac{1}{2} (- \frac{49}{5}) \cdot 1. 5^{2} = - \frac{441}{40}

= - \frac{25}{2} - \frac{441}{40}

- \frac{25}{2} - \frac{441}{40} = - \frac{941}{40}

= - \frac{941}{40}
