Question

can someone please send me the answer please please please​

Answer 1

Answer:

25a^2 - ( 9b^2 - 12bc + 4c^2)

= (5a)^2 - ( (3b)^2 - 2(3b)(2c) + (2c)^2))

= (5a)^2 - (3b - 2c)^2

= (5a + 3b - 2c)(5a - 3b + 2c)

Hope this helps you !

Answer 2

25$a^2$-9$b^2$+12bc-4$c^2$

=>25$a^2$-(9$b^2$-12bc+4$c^2$)

=>25$a^2$-$( (3a)^2-2*3b*2c+(2c)^2)$

=>$(5a)^2$-$(3b-2c)^2$

(5a-3b+2c)(5a+3b-2c)
