Step-by-step explanation:
Answer:
Option C.
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]
Option C will be the answer.
If te squre is inscribe in the cercle ten:The area of the circle is πR²
& the Area of te square is 2R², then the probability to land in the square :
2R²/πR²=2/π=0.6366 or 63.66%
Answer:
Step-by-step explanation:
= x^2+6x+9-8=0
=x^2+6x+1=0
D=b^2-4ac
D= 36-4
D=32
x=-b±root D/2a
x=-6+4root2/2 , x = -6-4root2/2
simplify you get the least form...
