The x coefficient is 2
Take half of 2 to get 2/2 = 1
Square 1 to get 1^2 = 1
Add and subtract 1 to the expression. This is the same as adding 0.
x^2 + 2x + 2
x^2 + 2x + 2 + 0
x^2 + 2x + 2 + (1-1)
(x^2 + 2x + 1) + 2 - 1
(x+1)^2 + 1
Answer: (x+1)^2 + 1
If you simplify the expression you will get 18x - 15.
Answer:
A-100
Step-by-step explanation:
Use the Pythagorean therom.
a^2+b^2=c^2
6^2+8^2=c^2
36+64=100.
Hope this helps. Kinda confused me.
You can group first two conjunctions and second two:
