The negative solution is -2.21 and positive solution is 12.21
<h3>Factorizing quadratic equations</h3>
Given the quadratic equation expressed as:
x^2-10x-27 = 0
Find the solution using the general formula
x^2-10x-27 = 0
x = 10±√(10)²-4(1)(-27)/2
x = 10±√100+108/2
x = 10±√208/2
x = 10±14.422/2
Simplify
x = 10+14.422/2 and x = 10-14.422/2
x = 24.422/2 and -4.422/2
x = 12.21 and -2.21
Hence the negative solution is -2.21 and positive solution is 12.21

anything to ask please pm me
D / 16 = t^2
when d = 64
64 /16 = t^2
t^2 = 4
t = 2
answer is 2 seconds
Answer:
The correct answer is (b).
Step-by-step explanation:
A line is parallel to the axis if it has a slope equal zero. Then if we compute the slope of the line that joins the points then
This implies that the line which that joins this points is parallel to the x-axis.
Observe that the slopes of the lines corresponding to the other items are nonzero.
