Answer:
Option C is the answer.
Step-by-step explanation:
Simon is factorizing the polynomial x² - 4x - 12 = (x - 6)( x + ......)
We will factorize the left hand side of the given expression
x² - 4x - 12
= x² - 6x + 2x - 12
Now we will break 12 into the factors so that sum of the factors should equal to 4
{ 6 × 2 = 12 and 6 - 2 = 4]
= x(x - 6) + 2(x - 6)
= (x + 2)(x - 6)
Therefore, the blank space should be replaced by 2.
Option C is the answer.
