Answer:
a) (x+2)^2-2
Step-by-step explanation:
write in form of x^2+2ax+a^2
2a=4
a=2
so
x^2+4x+2^2
we will now convert into the form:
x^2+2ax+a^2=(x+a)^2
substitute the values:
x^2+4x+2^2=(x+2)^2
(x+2)^2-2+2^2
(x+2)^2-2
Answer: (x + 2)2 − 2
Step-by-step explanation:
use the formula [tex](\frac{b}{2})^{2}[/tex] in order to create a new term and complete the square.
