Question

(ii) (x - 2)(x + 1) = (x - 1)(x + 3)
check check whether the following is quadratic equation or not full explanation please answer me ​

Answer 1

Answer:

this is the answer of this question.

Answer 2

Answer:

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

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

x² + x - 2x - 2 = x² + 3x - x - 3

x² - x - 2 = x² + 2x - 3

-x - 2 = 2x - 3

-x -2x = -3 + 2

-3x = - 1

x = 1/3

The given equation is not Quadratic ✅ when we comparing its General form (ax² + bx + c = 0)
