Question

(a²-b²=__________)
(a+b+c)²__________)
a³+b³________)
a⁴-b⁴_________
(a-b+c)²________​

Answer 1

Answer:

a²-b² = (a+b)(a-b)

(a+b+c)² = a²+b²+c²+2ab+2bc+2ac

a³+b³ = (a + b) (a2 - ab + b2 )

a⁴-b⁴=(a²+b²)(a+b)(a-b)

(a-b+c)² =a^2 + b^2 + c^2 -2ab -2bc + 2ca

Answer 2

Answer:

1)ab , 2)abc^2 , 3)ab^6 ,4)ab ,5)abc

Step-by-step explanation:

1)ab-2-2=0=ab

2)a+b+c^2=abc^2

3)a+b=ab/3+3=6=ab^6

4)a-b=ab/4-4=0=ab

5)a-b+c=abc/+ - = - , = abc
