Question 185856
x² + √22x = 0 
Is it x*sqrt(22)?  Or sqrt(22x)?
--------------

4/(m²-7) = 1 
Multiply by (m^2 - 7)
4 = m^2-7
m^2 = 11
m = +sqrt(11), -sqrt(11)
------------------
(y + 5)(y – 1) = 27
y^2 + 4y - 5 = 27
y^2 + 4y - 32 = 0
(y+8)*(y-4) = 0
y = -8, +4
----------------
Solve h = 16t² + vt + s for t.
16t^2 + vt +(s-h) = 0
t = -v/32 +- sqrt(v^2 - 64(s-h))/32
