To simplify the expression [tex]\(5x^2 + 3x^2\)[/tex], follow these steps:

1. Identify the common variable term: Both terms in the expression [tex]\(5x^2 + 3x^2\)[/tex] have the variable [tex]\(x^2\)[/tex].

2. Sum the coefficients: The coefficients are the numbers in front of the variable term. In this case, the coefficients are 5 and 3 respectively.

3. Add the coefficients together:
[tex]\[ 5 + 3 = 8 \][/tex]

4. Combine the sum with the variable term: Attach the combined coefficient to the common variable term [tex]\(x^2\)[/tex]:
[tex]\[ 8x^2 \][/tex]

Therefore, the simplified expression is:
[tex]\[ 8x^2 \][/tex]
