Answer: First option.
Step-by-step explanation:
You know that the product obtained by multiplying a binomial and a trinomial is:
Then, in order to simplify this product, it is necessary to add the like terms.
Therefore, the expression that is equivalent to this product after it has been fully simplified is:
You can observe that this matches with the first option.

Answer:
May be answer od your question is =
Do you see -8x?
Take half of -8 and square it.
So, (-8)/2 = -4.
(-4)^2 = 16
Now add 16 to both sides.
Answer:
x=-1 and x=5
Step-by-step explanation:
we have
Solve it by completing the square method
We take the coefficient of x that is -4, divide it by 2 and then square it
so
square it
Adds 4 both sides
Combine like terms right side
Rewrite as perfect squares
take square root both sides
therefore
