Question

(b+c-2a)(a+b-2c) solve by multiplication to obtain a equation

Answer 1

MULTIPLICATION

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

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

= ba+b^2 -2bc + ca+cb-2c^2- 2a^2-2ab+4ac

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

Process Involved

(a+b)(c+d) = ab + ad + bc + bd

(a-b)(c-d) = ac -ad- bc +bd
