Step-by-step explanation:
a(a+c)-b(b+c)
a2+ac-b2-bc
a2-b2=(a+b)(a -b)
Answer:
The answer of given factorisation is (a-b) (a+b+c).
Step-by-step explanation:
Given:
Find:
Need the formula:
Solution:
⏭ a(a+b) -b(b+c)
⏭ a^2 + ab - b^2 - bc
⏭ a^2 - b^2 + ab -bc
⏭ ( a+b)(a-b) +ab-bc
⏭ (a+b) (a-b) + c(a-b)
⏭ (a-b) (a+b+c)
