plz write the question properly

Answer 2

Answer:

-0.449 or 4.449

Step-by-step explanation:

to solve this we have used quadratic equation and linear equation

---------------------------------------------------------------------------------------------------

2(2x + 3) =x^2 +1

4x+3 = x^2+1

x^2+1=4x+3

x^2-4x=3-1

x^2-4x=2

x^2-4x-2=0

x =(4-√24)/2=2-√ 6 = -0.449

x =(4+√24)/2=2+√ 6 = 4.449
