To correctly insert grouping symbols into the expression 4 plus 3 times 2 squared plus 5, you need to consider the order of operations. Here's how you can do it step by step:

1. Start by identifying the part of the expression that should be prioritized. According to the order of operations (PEMDAS/BODMAS), exponents should be evaluated first.

2. The expression 2 squared means you need to square the value of 2, which gives you 4.

3. Replace 2 squared with the resulting value, 4, in the original expression: 4 plus 3 times 4 plus 5.

4. Next, evaluate the multiplication. Multiply 3 by 4, which equals 12.

5. Replace the multiplication with the resulting value, 12, and rewrite the expression: 4 plus 12 plus 5.

6. Finally, perform the addition. Add 4, 12, and 5 together to get the final result. The expression with grouping symbols would be: (4 + 12 + 5), which simplifies to 21.

So, the expression 4 plus 3 times 2 squared plus 5, with grouping symbols inserted, becomes (4 + 3 × 2^2 + 5) = 21.
