Question

check wether the following are quadratic equations
$(x - 2)(x + 1) = (x - 1)(x + 3)$
​

Answer 1

Given, (x−2)(x+1)=(x−1)(x+3)

⇒x(x+1)−2(x+1)=x(x+3)−1(x+3)

⇒x

2

+x−2x−2=x

2

+3x−x−3

⇒2x−2x−2−3x+3=0

⇒−3x+1=0

⇒−3x=−1

Hence, x=

3

1

A quadratic equation is of the form ax

2

+bx+c=0

Thus the above equation is not a quadratic equation.

Answer 2

Answer:

no

Step by step explanations:

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

x²-x-2=x²+2x-3

-2+3=2x+x

-1=3x

-3x-1=0

3x+1=0

so this is a linear equation
