Question

решите пожалуйста, сколько будет? ​

Answer 1

$48t {}^{2} - (12t - 4) \times (4t + 1) = - .$

$48t {}^{2} - (48t {}^{2} + 12t - 16t - 4) = - 2$

$48t {}^{2} - (48t {}^{2} - 4t - 4) = - 2$

$48t {}^{2} - 48t {}^{2} + 4t + 4 = - 2$

$4t + 4 = - 2$

$4t = - 2 - 4$

$4t = - 6$

$t = - \frac{6}{4}$

$t = - \frac{3}{2}$

$t = - 1,5$
