1. Chapter 14 Class 8 Factorisation
  2. Serial order wise


Ex 14.2, 1 Factorise the following expressions. (vi) 121𝑏^2 – 88bc + 16𝑐^2 121𝑏^2 – 88bc + 16𝑐^2 = (11𝑏)^2βˆ’88𝑏𝑐+(4𝑐)^2 = (11𝑏)^2βˆ’2Γ—11𝑏×4𝑐+(4𝑐)^2 = (11𝑏)^2+(4𝑐)^2βˆ’2Γ—11𝑏×4𝑐 Using (π‘₯βˆ’π‘¦^2 )=π‘₯^2+𝑦^2βˆ’2π‘₯𝑦 Here, π‘₯ = 11b and y = 4c = γ€–(πŸπŸπ’ƒβˆ’πŸ’π’„)γ€—^𝟐
