Question

Resolve the following into factor.
25a² + b² + 10ab - c²

Answer 1

Answer:

Step-by-step explanation:

25 a^2 + b^2 + 10 ab - c^2

(5a)^2 + 2×(5a)×(b) + (b)^2 - c^2

Using identity

x^2 + 2xy + y^2 = (x+y)^2

(5a + b)^2 - (c)^2

Using identity x^2 - y^2 = (x-y) (x+y)

(5a+b -c)(5a+b+c)

Answer 2

Answer:

I wish you get your answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

25 a^2 + b^2 + 10 ab - c^2

(5a)^2 + 2x(5a)×(b) + (b)^2 - c^2

Using identity

x^2 + 2xy + y^2 = (x+y)^2

(5a + b)^2 - (c)^2

Using identity

x^2 - y^2 = (x-y) (x+y) (5a+b -c)(5a+b+c)
