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

#SPJ1
the distributive property:
9(80+1)
to check the answer:
9 x 81 is 729
80 x 9 is 720
9 x 1 is 9
720+9=729
so the answer is right
the distributive property:
9(80+1)
Of what? There is not enough info
First multiply every thing by 7 to get rid of the fraction.
(y/7)(7) +6(7)=11(7)
y+42=77
y=35
