Question

Help please

Answer 1

The x term is 16x. The coefficient here is 16

Take half of this to get 16/2 = 8

Afterwards, square that result to get 8^2 = 64. This is the value you add to both sides

Notice how we get this

\[\Large x^2 +16x = 3\]
\[\Large x^2 +16x+64 = 3+64\]
\[\Large (x+8)^2 = 67\]
which has the left side as a perfect square

Answer 2

So simply 64 is the answer?

Answer 3

yes 64 is the final answer

Answer 4

yes the answer is 64
