Answer 1

Answer:

1) x² - 7x² + 12

⇒x⁴ - (4 + 3) x² + 12

⇒x⁴ - 4x² - 3x² + 12

⇒x² (x²- 4) -3 ( x² - 4)

⇒(x²- 4) (x²- 3)

⇒{(x)²- (2)²} (x² - 3)

⇒(x + 2) (x - 2) (x²-3 )

2) a² + 3a³b³ - 40b ⁶

⇒a⁶ + 8a³b³ - 5a³b³ - 40b⁶

⇒a³ ( a³+ 8b³) - 5b³(a³ + 8b³)

⇒(a³ + 8b³ ) (a³-5b³)

⇒{(a)³ + (2b)³} (a³-5b³)

⇒(a+ 2b) {a²-a.2b + ( 2b)² } (a³ - 5b³)

⇒(a + 2b)(a² - 2ab + 4b²)(a³ -5b³)
