Answer:
(a - b)(a + b)(a² + b²)(
+
)
Explanation:
by repeated use of the difference of squares factorising method, that is
a² - b² = (a - b)(a + b)
given
-
= (
)² - (
)²
= (
-
)(
+
) ← factor left parenthesis using difference of squares
= ( a² - b²)(a² + b²)(
+
) ← factor left parenthesis by difference of squares
= (a - b)(a + b)(a² + b² )(
+
)
