(a-2)² -(a+2)² =(a-2-a-2)(a-2+a+2)= -4 * 2a= - 8a
<span>Одна из первообразных этой функции равна F(x)=-1/3х³-7/2х²-10х-6
F(-2) = </span><span>-1/3 * (-2)³ - 7/2 * (-2)² - 10 * (-2) - 6 = . 8/3 - 14 + 20 - 6 = 8/3
</span>F(-5) = -1/3 * (-5)³ - 7/2 * (-5)² - 10 * (-5) - 6 = 125/3 -175/2 + 50 - 6 = -275/6 +44
<span>S = F(-2) - F(-5) = 8/3 - 44 + 275/6 = (275 + 16)/6 - 44 = 48,5 - 44 = 4,5</span>
