2) Раскрыть скобки:

$- 0.3 - 4.6 {a}^{2} + 4.1ab + 5.2 {a}^{2} - 1.4 {b}^{2}$

3) Привести подобные члены:

$- 0.3 + 0.6 {a}^{2} + 4.1ab + 1.4a {b}^{2}$

Answer 2

To add the two given expressions, you need to add the corresponding terms with the same variables and constants.

The first expression is (3-4, 6a^2+4, 1ab-3, 3) and the second expression is (5, 2a^2-1, 4b^2a).

Now, let's add the corresponding terms:

Constant terms: 3 + 5 = 8

Terms with 'a^2': 6a^2 + 2a^2 = 8a^2

Terms with 'ab': 1ab (which is simply 'ab') - no corresponding term in the second expression.

Terms with 'b^2a': No corresponding term in the first expression, but we have 4b^2a in the second expression.

So, the final expression after adding the two expressions is:

8, 8a^2, ab, 4b^2a
