Solution:
As per the problem given equation is,
[tex](\396.32 - \250) = \146.32[/tex]
[tex]\Rightarrow 2 \times x^{2}-60+10=0[/tex] (//substituting all at left)
[tex]\Rightarrow 2 \times x^{2}-50=0[/tex]
[tex]\Rightarrow 2 \times x^{2}=50[/tex]
[tex]\Rightarrow x^{2}=\left(\frac{50}{2}\right)[/tex]
[tex]\Rightarrow x^{2}=25[/tex]
So the value of x can be 5 and -5.
Hence one value of x can be 5 (proved).
