Answer:
a) x1 = 6 and x2 = -2
b) -2
Step-by-step explanation:
a)
To find the roots of the quadratic equation, we can use the Bhaskara's formula:
Delta = b^2 - 4ac
Delta = (-4)^2 - 4*1*(-12) = 64
sqrt(Delta) = 8
x1 = (-b + sqrt(Delta)) / 2a
x1 = (4 + 8) / 2
x1 = 6
x2 = (-b - sqrt(Delta)) / 2a
x2 = (4 - 8) / 2
x2 = -2
b)
The roots are 6 and -2, so the smaller root is -2
Answer:
The geometric figure is a Segment
Step-by-step explanation:
A and B are points since they are shown by dots and a point usually marks a location.
In Geometry a line is straight and extends in both directions infinitely.
A line segment or simply segment is the part of a line that connects two points. A segment is the shortest distance between the two points and has a length.

Answer:
<QRS= (10.x - 1) = (10.6 - 1) = 59°
Step-by-step explanation:
the triangle is not accurate but drawing one is truly useful in calculating. Besides, I don't know how it is called in English but it is something about the exterior angles (maybe)
