Question

factorize 16(a+b)^2-9(a-b)^2​

Answer 1

Answer:

STEP

1

:

Equation at the end of step 1

(16 • ((a + b)2)) - 9 • (a - b)2

STEP

2

:

Equation at the end of step 2

16 • (a + b)2 - 9 • (a - b)2

STEP

3

:

3.1 Evaluate : (a+b)2 = a2+2ab+b2

3.2 Evaluate : (a-b)2 = a2-2ab+b2

Trying to factor a multi variable polynomial :

3.3 Factoring 7a2 + 50ab + 7b2

Try to factor this multi-variable trinomial using trial and error

Found a factorization : (7a + b)•(a + 7b)

Final result :

(7a + b) • (a + 7b)

Answer 2

Answer:

(16+9)(a+b)²

25(a²+2ab+b²)

hope it is right
