Question

$(23 - x) ^2$
​

Answer 1

Step-by-step explanation:

$(23 - x) {}^{2}$

(a - b)2 formula is read as a minus b whole square. Its expansion is expressed as:-

$(a- b) ^2$ = $a {}^{2} - 2ab + b {}^{2}$

So,

$23 {}^{2} - 2 \times 23 \times x + x {}^{2}$

$529 - 46x + x {}^{2}$

Answer 2

Answer:

x²-46x+529

Step-by-step explanation:

$(23 - {x})^{2} = {23}^{2} - 2(23)(x) + {x}^{2}$

[using identity (a-b)²= a²-2ab+b²]

$529 - 46x + {x}^2$
