Answer 1

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 2

Answer: (x + 2)2 − 2

Step-by-step explanation:

use the formula $(\frac{b}{2})^{2}$ in order to create a new term and complete the square.
