As decimal answers:
x = -6.2749172 ≈-6.3
x = 1.27491722 ≈ 1.3
Step-by-step explanation:
For quadratic equations, you can use the quadratic formula. Rearrange the equation to standard from, which is ax² + bx + c = 0.
x² = –5x + 8
x² + 5x - 8 = 0
State the values for "a", "b" and "c",
a = 1; b = 5; c = -8
(Ignore the Â, it's a formatting error)
Simplify
Two negatives make a positive
Split the equation at the ± for plus and minus:
= 1.27491722 ≈ 1.3
= -6.2749172 ≈ -6.3
Therefore the solutions are 1.3 and -6.3.

Answer:
The value of H is 28.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(H-6)/(-7-(-5))
m=(H-6)/(-7+5)
-11=(H-6)/-2
-11(-2)=H-6
22=H-6
H=22+6
H=28
