Question

hmne 2 ×6 s =12 aaya ab Kya?
​

Answer 1

Answer:

X=6

Step-by-step explanation:

2x2+x-6=0

2x2+X=6

X(2x+1)=6

X=6

Answer 2

6*2 karo ...12 aa gya .,

12 ke aise factors kro ki multiply karne bar 12 aaye aur agar add ya subtract kare to x aa jaye.....

Clearly 3,4 hai aise factors 12 ke..

Ye upar wala rough work tha...

Now look,

=2x^2 + 4x - 3x - 6 = 0

(x ko 4x minus 3x likh sakte hai )

= 2x(x + 2) - 3(x + 2) = 0

* common ko ek bar likh lo

= (2x - 3)(x + 2) = 0

= 2x - 3 = 0.....& x +2 = 0

Therefore ,

x = 3/2 & x = -2...

Sab kuch ho gya ab muje brainest mark bhi kar do..
