Question

Factorize it plz do it now and semd it​

Answer 1

Answer:

= 16(a^2 + 2ab + b^2) - 9(a^2 -2ab + b^2)

= 16a^2 +32ab + 16b^2 - 9a^2 + 18ab - 9b^2

= 16a^2 - 9a^2 +32ab + 18ab + 16b^2 - 9b^2

= 7a^2 + 50ab +7b^2

Answer 2

Answer:

7a^2 + 50ab + 7b^2

Step-by-step explanation:

Considering (a+b) as "m" and (a-b) as "n"

16m^2 - 9n^2

(4m)^2 - (3n)^2

(4m+3n) (4m-3n)

Resubstituting the values of m and n

{4(a+b) + 3(a-b)} {4(a+b) - 3(a-b)}

{4a+4b+3a-3b} { 4a+4b-3a+3b}

{7a+b} {a+7b}

7a^2 + 49ab + ab + 7b^2

7a^2 + 50ab + 7b^2
