Which of the following is the standard representation of quadratic equation (x - 4)(x+1) = 2?

Correct option is A

Given:

(x-4)(x+1) =2

Solution:

Expanding the equation:

(x-4)(x+1) =2

​$$x^2 +x -4x -4 = 2$$​​

​$$x^2 -3x -4 -2 = 0$$​​

​$$x^2 -3x -6 = 0$$​​

Hence option (a) is correct representation
