Solve by middle term splitting methodx²-4x-12​

Answer»

rong>ANSWER :

  • x² - 4x - 12 = (X + 2) (x - 6)

GIVEN :

  • x² - 4x - 12

Solution :

》x² - 4x - 12

》x² - 6x + 2x - 12

》x(x - 6) + 2(x - 6)

》(x + 2) (x - 6)

Hence , x² - 4x - 12 = (x + 2) (x - 6)

or

》x² - 4x - 12

》x² - 6x + 2x - 12

》(x² - 6x) + (2x - 12)

》x(x - 6) + 2(x - 6)
