Ответ:

$3x + 6 = 0 \\ 3x = - 6 \\ x = - 2$

$\displaystyle \int_{ - 2} ^{1} 3x + 6dx = (3 \times \frac{ {x}^{2} }{2} + 6x)|_{ - 2} ^{1} = \frac{3 \times {1}^{2} }{2} + 6 \times 1 - ( \frac{3 \times {( - 2)}^{2} }{2} + 6 \times ( - 2)) = \frac{3}{2} + 6 - (6 - 12) = \frac{3}{2} + 6 - 6 + 12 = 13.5$ кв ед
