Question

Is (a–b)² = (b–a)² ?​

Answer 1

Answer:

yes

Step-by-step explanation:

(a-b) ^2=(b-a)^2

a^2+b^2-2ab=b^2+a^2-2ba

Answer 2

Answer:

No...... Mark it as brainliest please........

Step-by-step explanation:

Let a = 4 and b = 7

So, $(4-7)^{2}$ = $(7-4)^{2}$

$-3^{2}$ = $3^{2}$

-9 $\neq$ 9

Therefore (a–b)²$\neq$ (b–a)²

The reason why  $-3^{2}$ = -9 not 9 is

To evaluate -2^2 you perform the power operation first (2^2) before the negation so -2^2 = -(2^2) = -4. The order of operations is sometimes referred to as boardmas. If you want to express -2 times -2 using the power (sometimes called the exponential) notation you would write (-2)^2 since (-2)^2 = (-2) × (-2) = 4.
