Question

solve the linear equation (X + 2)( X + 3 )+ (X - 3 )(x- 2 )-2 X (X + 1 )=0​

Answer 1

Step-by-step explanation:

(x+ 2)( x + 3 )+ (x - 3 )(x- 2 )-2 x (x+ 1 )=0

x^2 + 3x + 2x +6 +(x^2 -2x -3x +6) - 2x^2 -2x =0

x^2 + 3x + 2x +6 + x^2 -2x -3x +6 - 2x^2 -2x =0

2x^2 - 2x^2 + 5x - 5x -2x + 12 =0

some terms are cancelling

-2x +12 = 0

-2x = -12

-x = -6

x = 6
