Question

The square of the binomial (2x3- 3y3)

Answer 1

(2x³-3x³)²
=(2x³)²+(3x³)²-2(2x³)(3x³)

${=4x^6+9x^6-12x^6}$

$={12x^6-12x^6}$

Answer=0

Answer 2

Answer:

Step-by-step explanation:

Let,2x3 = 6x = a

And,3y3 = 9y = b

Then square of the above equation in the question will be,

(6x-9y)² = 36x²-108xy+81y²

[ (a-b)²=a²-2ab+b²]

÷ing equation with 3 =>

12x²-36xy+27y²

=4x²-12xy+9y²

So, the square of the above equation in the question will be,

4x²-12xy+9y²
