Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
x^2 = -5x + 8
:
I'm not sure what you have got here, the above equation will not factor, anyway,
put in the ax^2 + bx + c = 0 form.
x^2 = -5x + 8
:
x^2 + 5x = 8; added 5x to both sides
x^2 + 5x - 8 = 0; subtracted 8 from both sides
:
There are no integer factors so use the quadratic formula:
Here it is step-by-step:
In this equation a = 1; b = 5; c = -8
Two solutions:
x = +1.275
and
x = -6.276

Are these supposed to be other problems; Let me know, and what you need help
with.
:
(x+3)(x+4)=0
x=-3
x^2=16
x^2=16=0
