If 39 = (1 3/10)b, we could simplify this by writing 39 - (13/10)b.

Solve this for b by mult. both terms by (10/13):

(10*39)
----------- = (10/13)(13/10)b.  Then b = 30 (answer)

Answer:

\boxed{\sf x=\cfrac{1\pm \sqrt{-7} }{2}}

Step-by-step explanation:

\sf x^2-x+2=0

<u>Use quadratic formula:</u>

\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac}}{2a}}

\sf a=1, b=-1, c=2

___________________________

\sf x_1,_2=\cfrac{-\left(-1\right)\pm \sqrt{\left(-1\right)^2-4\times \:1\times \:2}}{2\times \:1}

  • \sf \sqrt{\left(-1\right)^2-4\times \:1\times \:2}
  • \sf =\sqrt{-7}

_________________

\sf x_1,_2\cfrac{-\left(-1\right)\pm \sqrt{-7}}{2\times \:1}

  • \sf -(-1)=1
  • 2\times 1=2

\sf x_1,_2=\cfrac{1\pm \sqrt{-7} }{2}
