Ex 2.1, 2 Write the coefficients of π₯2 in each of the following: (i) 2 β π₯2 + π₯ 2 β π₯2 + π₯ = 2 β1Γπ₯2 + π₯ πΆππππππππππ‘ ππ π₯2 = β1 Ex 2.1, 2 Write the coefficients of π₯2 in each of the following: (ii) 2 β π₯2 + π₯3 2 β π₯2 + π₯3 =2β1 Γ (π₯2) + π₯ πΆππππππππππ‘ ππ π₯2 = β1 Ex 2.1, 2 Write the coefficients of π₯2 in each of the following: (iii) π/2 π₯2 + π₯ π/2 π₯2 + π₯ = π/2 Γ π₯2 + π₯ Coefficient of π₯2 = π/2 Ex 2.1, 2 Write the coefficients of x2 in each of the following: (iv) β2 π₯ β 1 There is no x2 So we will create π₯2 in above equation by adding 0 β2 π₯ β 1 = 0 + β2 π₯ β 1 = 0.π₯2 + β2 π₯ β 1 Zero is multiplied to π₯2 Coefficient of π₯2 = 0.
