78. ∫⁵₁ ( x² - 5x ) dx
[tex] = \frac{1}{2 + 1} x {}^{2 + 1} - \frac{5}{1 + 1} x {}^{1 + 1} \\ = \frac{1}{3} x {}^{3} - \frac{5}{2} x {}^{2} [/tex]
= ⅓( 5³ - 1³ ) - 5/2 ( 5² - 1² )
= ⅓( 125 - 1 ) - 5/2( 25 - 1 )
= ⅓.124 - 5/2. 24
[tex] = \frac{124}{3} - 60 \\ = \frac{124 - 180}{3} = - \frac{56}{3} \\ = - 18 \frac{2}{3} (e.)[/tex]
