That is the answer to the question.

The guest must be greater than or equal to 42.5 inches.
Gg easy
remember
for
ax^2+bx+c=0
first
minus c from both sides
ax^2+bx=-c
divide both sides by a (disregard if a=1)
take 1/2 of b and square it and add that to both sides
factor perfect square
ok so
x^2-3x=-1
-3/2=-1.5
(-1.5)^2=2.25
add that to both sides
x^2-3x+2.25=2.25-1
factor
(x-1.5)^2=1.25
