Question

solve by middle term splitting method
x²-4x-12​

Answer 1

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)

》(x - 6) (x + 2)

Answer 2

Answer:

x^2 - 6x + 2x - 12. = 0 [the 4 is splited in (-6,2)]

x(x-6) + 2(x-6) = 0 [taking (x) common in first and taking 2 common in second]

(x+2) (x-6)

x + 2 = 0. x - 6 = 0

therefore, x= -2,6
