Answer: -1 ± <em>i</em>√35
⁻⁻⁻⁻⁻⁻⁻⁻
6
Step-by-step explanation:
From the quadratic equation,
X = -b ±√b² - 4ac
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2a
From the given equation, -3x² - x - 3 = 0
where a = -3, b = -1, c = -3
Now substitute for the values in the formula above
x = -(-1) ± √(-1)² - 4(-3)(-3)
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2(-3)
x = 1 ± √ 1 - 36
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = 1 ± √ -35
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = -1 ± <em>i√35 this is because it has a negative root.</em>

A Rectangle Is A 4 Sided Closed Figure That Has 4 Right Angles, While A Rhombus Does Not Have Any Right Angles
Answer:
The length of the three sides 
The triangle <u>is not</u> a right triangle
Step-by-step explanation:
A = (3, 2) , B = ( 6, 9) , C = (10, 6)
Find the lengths using distance formula.
Using Pythagoras theorem :
Longest side is AC . So we will check if it satisfies Pythagoras theorem :
65 ≠ 58 + 25
So the sides does not satisfy Pythagoras theorem. Hence the triangle is not a right triangle.
