Answer:

Look below.

Step-by-step explanation:

No, the method of quadratic equations doesn't apply for all equations. This is because the quadratic formula can only be used to solve any quadratic equation when it's in standard form. Some equations arent in the format of ax2 + bx + c = 0, meaning that you cant use these mothods on any equation.

The given is that A B C D <span>x 4 = D C B A
</span><span>
Possible values of A are 1 or 2. It can't be 1 since the </span><span> </span><span>final result A is in unit place and 1 is not possible when we multiply any number by 4
</span><span>
2 B C D x </span><span>4 = </span><span>D C B 2</span>
It is clear above, that D = 8
2 B C 8 x <span>4 = </span><span>8 C B 2</span>
Possible values of B should be 1 or 2
We try B=1

2 1 C 8 x <span>4 = </span><span>8 C 1 2

</span>To find for C, you can use the equation:

(2000+100+10C+8) x 4 = 8000+100C+10+240C = 432-12 = 420
Therefore,

C = 7
So, the number is 2178.
