Answer:
(x-3)² = 23 Option B
Step-by-step explanation:
Given quadratic is :
x² - 6x - 14 = 0
Use complete the square method
Move loose term from left side to right side.
x² - 6x = 14
add both the side square of half coefficient of x that is,
half of -6 = -3
square of -3 = 9
Add both the side 9
x² - 6x + 9 = 14 + 9
(x - 3)² = 23
this is same as (x-3)²=23 second option
That's the final answer.
B
11+7=18
no solution
2x-5=8x+7-6x
2x-5=2x+7
-5=7
Not true so no solution
your answer is as follows
5x+20=3x+60
2x=40
x=20
(equating the slopes)
