Evaluate : (a^2 + 5) (a^2 - 3)

(a 2 \+ 5) (a 2 \- 3) = a 2 (a 2 \- 3) \+ 5 (a 2 \- 3) = a (2+2) \- 3a 2 \+ 5a 2 \- 15 = a 4 \+ 2a 2 \- 15 Hence, (a 2 \+ 5) (a 2 \- 3) = a 4 \+ 2a 2 \- 15

Answer

(a² + 5) (a² - 3)

= a² (a² - 3) + 5 (a² - 3)

= a⁽²⁺²⁾ - 3a² + 5a² - 15

= a⁴ + 2a² - 15

Hence, (a² + 5) (a² - 3) = a⁴ + 2a² - 15
