Answer 1

Answer:

make me brainlist

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

+3x−x−3

⟹x

+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..

Answer 2

Answer:

Step-by-step explanation:

(x-2) (x+1) = (x-1) (x+3)​

x²+x-2x-2=x²+3x-x-3

-x-2=2x-3

3x=1

x=1/3
