Factor the expression completely.16, x, squared, plus, 5616x 2 +56

The expression you provided seems to be a bit unclear. However, if you're asking to factor the expression "16x^2 + 56", here's how you do it:

Step 1: Identify the greatest common factor (GCF). In this case, the GCF of 16x^2 and 56 is 8.

Step 2: Divide each term by the GCF and rewrite the expression. This gives us 8(2x^2 + 7).

So, the expression "16x^2 + 56" factored completely is "8(2x^2 + 7)".

It seems like there might be a mistake in your question. The expression you provided "16, x, squared, plus, 5616x 2 +56" is not clear.

If you meant "16x^2 + 5616", then here's how you can factor it:

Step 1: Identify the common factor The common factor in this case is 16.

Step 2: Factor out the common factor 16(x^2 + 351)

Step 3: Check if the expression inside the parentheses can be factored further The expression x^2 + 351 cannot be factored further using real numbers.

So, the completely factored form of the expression 16x^2 + 5616 is 16(x^2 + 351).
