Answer 2

Answer:

Solution :-

★ x(x - 4) = 12

➞ x² - 4x = 12

➞ x² - 4x - 12 = 0

➞ x² - (6 - 2)x - 12 = 0

➞ x² - 6x + 2x - 12 = 0

➞ x(x - 6) + 2(x - 6) = 0

➞ (x - 6) (x + 2) = 0

➞ (x - 6) = 0

➞ x - 6 = 0

➞ x = 6

Either,

➞ (x + 2) = 0

➞ x + 2 = 0

➞ x = - 2

∴ The answer of this question is 6, - 2
