Question

plz........................?....!!......!

Answer 1

(1)...2a^2-2ab+bc-ac
2a(a-b)-c(a-b)
(a-b)(2a-c)


(2)...2a(4b^2-9a^2)
is your answer

Answer 2

(1)

Given Equation is 2a^2 + bc - 2ab - ac

= > 2a^2 - ac - 2ab + bc

= > a(2a - c) - b(2a - c)

= > (a - b)(2a - c)


(2)

Given Equation is 8ab^2 - 18a^3

= > 2a(4b^2 - 9a^2)

= > 2a((2b)^2 - (3a)^2)

= > 2a(3a + 2b)(3a - 2b).



Hope this helps!
