Answer 1

Answer:

( a + 2b ) ( 3a + b ) - ( a + b ) ( a + 2b ) + ( a + 2b )²

3a² + ab + 6ab + 2b² - a² + 2ab + ab+ 2b²+ (a+2b)²

Answer 2

Step-by-step explanation:

17. 6xy(a²+b²) + 8yz(a²+b²) - 10xz(a²+b²)

= (a²+b²)(6xy+8yz-10xz)

= (a+b)(a-b)×2(3xy+4yz-5xz)

= 2(a+b)(a-b)(3xy+4yz-5xz)

16. (a+2b)(3a+b)-(a+b)(a+2b)+(a+2b)²

= (a+2b){(3a+b)-(a+b)+(a+2b)}

= (a+2b)(3a+b-a-b+a+2b)

= (a+2b)(3a+2b)
