Mathematics
1 answer:
vesna_86 [32]3 years ago
8 0

Answer:X1=1+-1+i(2)^1/2

x2=-1-i(2)^1/2

Step-by-step explanation

y=y

-2x+1=-x^2+4

x^2+4+2x-1=0

x^2+2x+3=0

Use

Ax^2+Bx+C=0

X1,X2=[-B+(B^2-4*A*C)^1/2]/2*A

A=1

B=2

C=3

x=[-2+/-(2*2-12)^1/2]/2

x=[-2+/-(-8`)^1/2]/2

x=[-2+/-2i(2)^1/2]/2

x1=-1+i(2)^1/2

x2=-1-i(2)^1/2
