I need assistance, I get very weird answers, I feel my method of working is incorrect!
Thanks.

I would use the bisection method to solve
f(x) = 1.5^x + (sqrt X) -10 = 0
where you basically choose initial bounds which you know contain the solution. Then you repeatedly reduce those bounds in half using the values of f(x) to determine which half contains the solution.
After a few calculations I found your result is between
5 and 6
f(5) = -0.17
f(6) = 3.84
keep going with bisection until you have the desired accuracy.
Alternatively the secant method might be a better choice.

a million. Does X^2 +15x +50 = 0?? if so, factor: (x+5)(x+10) if x+5 = 0 then one answer for x is -5; if x+10 = 0 the different answer for x = -10 2. X^2 -24 = 0 rearrange X^2 = 24, and x = sq. root of 24
