Question

Преобразуйте в многочлен : ( 0,2 а + b ) ^ 2 решите пример пожалуйста кто - нибудь

Answer 1

( 0,2 а + b ) ^ 2 = 0,04a^2 + 0,4ab + b^2

Answer 2

(0,2a+b)^2=0,04a^2+0,4ab+b^2

Answer 3

Converting to a Polynomial:

To convert the expression (0.2a + b)^2 into a polynomial, we can use the formula for squaring a binomial, which is (a + b)^2 = a^2 + 2ab + b^2. Applying this formula to the given expression, we get:

Polynomial: (0.2a + b)^2 = (0.2a)^2 + 2 * (0.2a) * b + b^2

Simplifying the Polynomial:

Now, let's simplify the polynomial by performing the necessary calculations:

(0.2a)^2 = 0.04a^2 2 * (0.2a) * b = 0.4ab b^2 = b^2

So, the simplified polynomial is: 0.04a^2 + 0.4ab + b^2

Solution:

The expression (0.2a + b)^2, when expanded, simplifies to the polynomial 0.04a^2 + 0.4ab + b^2.
