Question

शून्यक ज्ञात कीजिए
x2-2x-8

​

Answer 1

Answer:

x²- 2x - 8

x²+2x-4x-8

x(x+2) -4(x+2)

(x-4) (x+2)

Thus when we compare both of it with 0 we get:

x = 4

x = -2

Answer 2

Answer:

${x}^{2} - 2x - 8 \\ {x }^{2} - (4 - 2)x -8 \\ {x}^{2} - 4x + 2x - 8 \\ x(x - 4) + 2(x - 4) \\ (x - 4)(x + 2) \\ x - 4 = 0 \\ x = 4 \\ x + 2 = 0 \\ x = - 2$
