1.4 is what fraction of a feral bar each boy gets
The correct factor is (x - 2) and (x + 1).
<h2>Quadratic equation</h2>
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
Given
x² - x - 2 = 0 is a quadratic equation.
<h3>To find </h3>
The factor of the given equation.
<h3>How to find the factor of the given equation?</h3>
x² - x - 2 = 0 is a quadratic equation.
According to factorization,
x² - x - 2 = 0
x² - 2x + x - 2 = 0
x(x - 2) +1 (x - 2) = 0
( x - 2 ) ( x + 1 ) = 0
Thus the correct factor is (x - 2) and (x + 1).

Answer:
2nd option
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle
sin82° =
=
=
( multiply both sides by
)
× sin82° = KL , then
KL ≈ 3.28 ( to the nearest hundredth )
cos82° =
=
=
( multiply both sides by
)
× cos82° = ML , then
ML ≈ 0.46 ( to the nearest hundredth )
------------------------------------------------------------
The sum of the 3 angles in a triangle = 180° , so
∠ K = 180° - (90 + 82)° = 180° - 172° = 8°
I hope this helps you
x^2-6x+9= -1
(x-3)^2= -1
(x-3)^2=i^2
x-3=i
x=3+i
x=3-i
or we can find disctirminant
x^2-6x+10=0
a=1
b= -6
c=10
disctirminant=b^2-4ac
disctirminant=(-6)^2-4.1.10
disctirminant=36-40
disctirminant= -4
i^2= -1
x1,2= -b (+,-) square root of disctirminant /2a
x1= -(-6)+square root of -4/2.1
x1=6+2i/2=3+i
x2= -(-6)-square root of -4/2.1
x2=6-2i/2=3-i
