Answer:
2b(a+b)
Step-by-step explanation:
(a+b)²-a²+b²=a²+2ab+b²-a²+b²=2ab+2b²=2b(a+b)
Answer:
the factorisation is : 2b(b+a)
Step-by-step explanation:
(a+b)²-a²+b² = (a+b)²+(b²- a²)
= (b+a)²+(b - a)(b +a)....because : a+b =b+a and : b²- a²=(b - a)(b +a).
the factor is : b+a
(a+b)²-a²+b² = (b+a)((b+a)+(b-a))
(a+b)²-a²+b² = (b+a)(2b)
the factorisation is : 2b(b+a)
