Answer 2

In algebra, "SOS" stands for "Sum of Squares." To find the square of a binomial expression like (3x^6 - 0.7y^2)⋅(3x^6 + 0.7y^2), you need to use the formula for the square of a binomial:

(a + b)^2 = a^2 + 2ab + b^2

In this case, a = 3x^6, and b = 0.7y^2. Now, let's apply the formula:

(3x^6 - 0.7y^2)⋅(3x^6 + 0.7y^2) = (3x^6)^2 + 2(3x^6)(0.7y^2) + (0.7y^2)^2

Now, let's simplify each term:

(3x^6)^2 = (3x^6)(3x^6) = 9x^(6+6) = 9x^12

2(3x^6)(0.7y^2) = 2 * 3 * 0.7 * x^6 * y^2 = 4.2x^6y^2

(0.7y^2)^2 = 0.7^2 * y^(2*2) = 0.49y^4

Now, put it all together:

(3x^6 - 0.7y^2)⋅(3x^6 + 0.7y^2) = 9x^12 + 4.2x^6y^2 + 0.49y^4

This is the square of the given binomial expression.
