Question

find the solution for the following equation x²-4x-12=0​

Answer 1

Answer:

by factorizing it

x^2 -2x +6x -12 = 0

x(x-2) +6(x-2) =0

(x+6)(x-2)=0

x= (-6,2)

Answer 2

Answer:

x²- 4x - 12 = 0​

Sum = -4 = -6 + 2

Product = -12 = -6 x 2

x² - 6x + 2x - 12 = 0

x(x - 6) + 2(x - 6) = 0

(x + 2)(x - 6) = 0

x + 2 = 0, x = -2

x - 6 = 0, x = 6
