Question

Factorise as negative values inside: z2-3z+2=0​

Answer 1

Step-by-step explanation:

$z^{2}$ - 3z+2=0

$z^{2}$ -2z-z +2 =0 (by splitting the middle term)

z(z-2)   -1(z-2) (taking common term in both the equation)

(z-2)(z-1)

z=2,1

I,hope it will help you

Answer 2

z^2 -3z + 2 =0

z^2 -2z -z + 2 =0 { by splittong middle term}

z{z-2} -1{z-2} { taking common term }

{ z-2} { z-1}

so , z = 2,1
