Question

Factorise the following polynomial
1. z(z-1)+2(z-1)​

Answer 1

Answer:

z²+z-2.................

Answer 2

Answer:

${z}^{2} - z + 2z - 2 \\ = {z}^{2} + z - 2 \\ = {z}^{2} + 2z - z - 2 \\ = z(x + 2) - 1( z+ 2) \\ = (z - 1)and \\ (z + 2) \\ i \: hope \: you \: anderstand \: \\ \\ mark \: the \: brainliest \: \: dear$
