Question

2(a - b)²=???????????? ​

Answer 1

$2\cdot\Big(a-b\Big)^2=2\cdot\Big((a)^2-2\cdot a \cdot b + (b)^2 \Big)=2\cdot a^2+2\cdot\Big(-2ab\Big)+2\cdot b^2=2a^2-4ab+2b^2$

Answer 2

2(a - b)² = 2(a² - 2ab + b²) = 2a² - 4ab + 2b²

Answer 3

To find the expression for 2(a - b)², we need to apply the square of a binomial formula. The square of a binomial (a - b)² is given by:

(a - b)² = a² - 2ab + b²

Now, we have 2 multiplied by the square of (a - b):

2(a - b)² = 2(a² - 2ab + b²)

We can also simplify this expression by distributing the 2 across the terms inside the brackets:

2(a - b)² = 2a² - 4ab + 2b²

So, 2(a - b)² is equal to 2a² - 4ab + 2b².
