Factorise X2 2xy Y2 Z2 Gauthmath Factorise using identities 4x2y2 – 4xyz z2 Factorise using identities 4x2y2 – 4xyz z2 4x 2 y 2 – 4xyz z 2 From of identity, xy = a, z = b (2a – b) 2 ∴ (2xy – z) 2 0;X22xyy22x2y1=0 No solutions found Step by step solution Step 1 Trying to factor by pulling out 11 Factoring x22xy2xy22y1 Thoughtfully split the expression at hand into If the Factorise ∶ − (x 2 − 2xy + y 2 ) 2 − z 2
