Evaluate: (a + b) (a - b) (a^2 + b^2)

(a \+ b) (a \- b) (a 2 \+ b 2 ) Using the formula [∵ (x \+ y)(x \- y) = x 2 \- y 2 ] = (a 2 \- b 2 ) (a 2 \+ b 2 ) = a 4 \- b 4 Hence, (a \+ b) (a \- b) (a 2 \+ b 2 ) = a 4 \- b 4

Answer

(a + b) (a - b) (a² + b²)

Using the formula

[∵ (x + y)(x - y) = x² - y²]

= (a² - b²) (a² + b²)

= a⁴ - b⁴

Hence, (a + b) (a - b) (a² + b²) = a⁴ - b⁴
