Ex 9.5, 1 Use a suitable identity to get each of the following products. (i) (π‘₯+3) (π‘₯+3) (π‘₯+3) (π‘₯+3) = (π‘₯+3)^2 (π‘Ž+𝑏)^2=π‘Ž^2+𝑏^2+2π‘Žπ‘ Putting π‘Ž = π‘₯ & 𝑏 = 3 = π‘₯^2+3^2+2(π‘₯) (3) = 𝒙^𝟐+πŸ—+πŸ”π’™ Ex 9.5, 1 Use a suitable identity to get each of the following products. (ii) (2𝑦 + 5) (2𝑦 + 5) (2𝑦+5) (2𝑦+5) = (2𝑦+5)^2 (π‘Ž+𝑏)^2=π‘Ž^2+𝑏^2+2π‘Žπ‘ Putting π‘Ž = 2𝑦 & 𝑏 = 5 (π‘Ž+𝑏)^2=π‘Ž^2+𝑏^2+2π‘Žπ‘ Putting π‘Ž = 2𝑦 & 𝑏 = 5
