Question

from the chapter
FACTORIZATION OF ALGEBRAIC EXPRESSIONS

1.factorize the following using identities.
$9 {a}^{4} - 24 {a}^{2} {b}^{2} + 16 {b}^{4} - 256 {a}^{2}$
​

Answer 1

Answer:

9a⁴-24a²b²+16b⁴-256a²

9a⁴-12a²b²-12a²b²+16b⁴-256a²

3a²(3a²-4b²)-4b²(3a²-4b²)-(16a)²

(3a²-4b²)(3a²-4b²)-(16a)²

(3a²-4b²)²-(16a)²

(3a²-4b²-16a)(3a²-4b²+16a)
