I need help with my zero calculation?
I don't know exactly what task b) should look like after I calculate :(-1) at the beginning.
Looking forward to the answers,

x^2 – 5x + 4 = 0
And now the pq formula
0 = -x2 + 5x – 4 |(-1)
0 = x2 – 5x + 4
pq-formrl with p= -5 and q= +4. Or abc formula, it would have been possible to share it but to save it.
You need to use the PQ formula.
Can use the abc formula
