Ex 12.2, 4 Factorise. (v) π^4 β 2π^2 π^2 + π^4 π^4 β 2π^2 π^2 + π^4 = (π^2 )^2 β 2π^2 π^2+(π^2 )^2 = (π^2 )^2 +(π^2 )^2β2 (π^2Γπ^2 ) Using (π₯ β y)^2=π₯^2+π¦^2 β 2xy Here π₯=π^2 and y = π^2 = (π^2 β b^2 )^2 Using π₯^2 β y^2=(π₯+π¦)(π₯ β y) Here π₯=π and y = π = [(π+π) (π β b)]^2 = (π+π)^π (π β π)^π (As (ππ)^π=π^πΓπ^π)
