Question

30. Factorine using suitable algebraic identities
a*-(2b+2bc+c*)​

Answer 1

Answer:

a(a−2b−c)+2bc

Step-by-step explanation:

Given : a(a−2b−c)+2bc

By multiplying the terms

a(a−2b−c)+2bc =a

2

−2ab−ac+2bc

By taking the common terms out

a(a−2b−c)+2bc =a(a−2b)−c(a−2b)

So we get,

a(a−2b−c)+2bc =(a−c)(a−2b)
