(a^2+b^2)(c-d)(a-2b) please solve it till end.

Answer: a2 - 2ab + b2 - c2 + 2cd - d2
Step-by-step explanation: Step 1 :
1.1 Evaluate : (a-b)2 = a2-2ab+b2
1.2 Evaluate : (c-d)2 = c2-2cd+d2
Trying to factor by pulling out :
1.3 Factoring: a2-2ab+b2-c2+2cd-d2
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 2cd-c2
Group 2: -2ab+a2
Group 3: b2-d2
Pull out from each group separately :
Group 1: (c-2d) • (-c)
Group 2: (a-2b) • (a)
Group 3: (b2-d2) • (1)
Looking for common sub-expressions :
Group 1: (c-2d) • (-c)
Group 3: (b2-d2) • (1)
Group 2: (a-2b) • (a)
Kindly someone atleast mark me as brainliest. please friends
Answer:
a³c - 2a²bc - a³d + 2a²bd + ab²c - 2b³c - ab²d + 2b³d
Step-by-step explanation:
(a² + b²)(c - d)(a - 2b)
= (a² + b²){c(a - 2b) - d(a - 2b)}
= (a² + b²){ac - 2bc - ad + 2bd}
= a²(ac - 2bc - ad + 2bd) + b²(ac - 2bc - ad + 2bd)
= a³c - 2a²bc - a³d + 2a²bd + ab²c - 2b³c - ab²d + 2b³d
