Step-by-step explanation:
If (x - 1)(x + 6) - (x - 2)(x - 3) = 3
then,
⇒ x2 + 6x - x - 6 - {x2- 3x - 2x + 6} = 3
⇒ x2 + 5x - 6 - x2 + 5x - 6 = 3
⇒10x - 12 = 3
⇒10x = 15
⇒ x = 15/10
∴x = 3/2

Answer:
(x - 1)(x + 6) - (x - 2)(x - 3) = 3
x (x + 6) - 1 (x + 6) - x (x - 3) + 2 (x - 3) = 3
x^2 + 6x - x - 6 - x^2 + 3x + 2x - 6 = 3
x^2 - x^2 + 6x - x + 3x + 2x - 6 - 6 = 3
10x - 12 = 3
10x = 3 + 12
x = 15/10
x = 3/2
So, the answer is 3/2
