Answer:
Step-by-step explanation:
According to the equation, we have to solve for x :
x² - 10x + 25 = 35
x² - 10x + 25 - 35 = 0
x² - 10x - 10 = 0
Using Quadric Formula,
x = - b ±√b²-4ac / 2a
x = - (-10) ±√(-10)² - 4(1)(-10) / 2(1)
x = 10 ±√ 100 + 40 / 2
x = 10 ±√ 140 / 2
Taking common "2"
x = 2 (5±√70) / 2
Both "2" will cut with each other
So,
Now we have
x = 5 ± √70
This is the required "X" In the equation
