 \huge \underline \bold \pink{Solution : }

(x - 2)(x + 1) = (x - 1)(x + 3) \\  \\  =  >  {x}^{2}  + x - 2x - 2 =  {x}^{2}  + 3x - x - 3 \\  \\  =  >  - x - 2 =  2x - 3 \\  \\  =  > 2x + x = 3 - 2 \\  \\  =  > 3x = 1 \\  \\  =  > x =  \frac{1}{3}

Answer:

Given equation (x−2)(x+1)=(x−1)(x+3)

To find whether the given equation is a quadratic equation or not

Sol:

(x−2)(x+1)=(x−1)(x+3)

⟹x ² +x−2x−2=x² +3x−x−3

⟹x²−x²+x−2x−3x+x−2+3=0

⟹−3x+1=0

This is not a quadratic equation as an equation of degree two is called a quadratic equation.

And, a polynomial when equated to zero or some value becomes an equation.
