If you subtract a number x from 22 times that number,and then take the square of the differnce,what will the result be?

Respuesta :

Let us try to make an expression from the given information:

22 times the number x would be 22x

subtract x from 22 times x would be 22x-x which is equal to 21x

now taking square of difference:

(21x)²

(21x)² =21x * 21x

multiplying 21 with 21 and x with x

21*21 =441

x*x =x²

so

(21x)² = 441x²
