Answer:
-(x^2-2x+4)=0
Step-by-step explanation:
Standard form: ax^2+bx+c=0
Add 5 to both sides: 2x^2=2x+x^2-4
Subtract 2x^2 from both sides: 0=2x-x^2-4
Switch sides: 2x-x^2-4=0
Arrange the left side into standard form: -x^2+2x-4=0
Since there's a negative for the x^2, factor it out: -(x^2-2x+4)=0
I hope this helped! Have a good rest of your day!
