Rewrite the following expression so that it is properly formatted and makes sense:

[tex] (0, 2x^2 + 5y^2 + 2)^2 [/tex]

As written, the expression appears to include a comma, which may not be appropriate in this context. A more reasonable expression might be:

[tex] (2x^2 + 5y^2 + 2)^2 [/tex]

Please verify the intended expression to ensure accuracy.


Sagot :

Sure! Let's solve the given expression step by step. We want to find the square of the expression:

[tex]\[(0, 2x^2 + 5y^2 + 2)\][/tex]

We are specifically interested in squaring only the second part of the tuple:

[tex]\[2x^2 + 5y^2 + 2\][/tex]

Our goal is to compute:

[tex]\[\left(2x^2 + 5y^2 + 2\right)^2\][/tex]

To square the expression, we use the identity [tex]\((a + b + c)^2 = a^2 + b^2 + c^2 + 2ab + 2ac + 2bc\)[/tex]. Let's apply this step by step.

Here, [tex]\(a = 2x^2\)[/tex], [tex]\(b = 5y^2\)[/tex], and [tex]\(c = 2\)[/tex].

1. Square each term individually:
[tex]\[ (2x^2)^2 = 4x^4 \][/tex]
[tex]\[ (5y^2)^2 = 25y^4 \][/tex]
[tex]\[ 2^2 = 4 \][/tex]

2. Compute the cross-product terms:
[tex]\[ 2 \cdot (2x^2) \cdot (5y^2) = 20x^2y^2 \][/tex]
[tex]\[ 2 \cdot (2x^2) \cdot 2 = 8x^2 \][/tex]
[tex]\[ 2 \cdot (5y^2) \cdot 2 = 20y^2 \][/tex]

3. Combine all the terms:
[tex]\[ (2x^2 + 5y^2 + 2)^2 = 4x^4 + 25y^4 + 4 + 20x^2y^2 + 8x^2 + 20y^2 \][/tex]

Thus, the final squared expression is:

[tex]\[\left(2x^2 + 5y^2 + 2\right)^2\][/tex]

Simplified, it remains:

[tex]\[\left(2x^2 + 5y^2 + 2\right)^2\][/tex]
