Answer:
Option B
Step-by-step explanation:
Given: x² + 10x + 13
To make a complete square, we will use (b/2)² to add terms to complete the square where b is the coefficient of x
b = 10 , (b/2)² = 5² = 25
So, add 25 and subtract 25
x² + 10x + 13
= x² + 10x + 13 + 25 - 25
= (x² + 10x + 25) + 13 -25
= (x+5)² - 12
By comparing the options with the previous steps
So, the answer is <u>option B</u>
A good amount I suppose :)
