Answer:
x=-6.192
and
x=-0.807
Step-by-step explanation:
1) turn this into a quadratic equation by moving it to the "10" to the right:
-x^2+7x-5=0
now quadratic equations are in the form of:
ax^2+bx+c
so substitute a=1
b=7
and c=-5 in the quadratic formula: [tex]\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]
so
[tex]\frac{7+/-\sqrt{29} }{-2}[/tex]
lets do addition first:
so
(7+[tex]\sqrt{29}[/tex])/-2=-6.19258240357
lets do subtraction next:
(7-[tex]\sqrt{29}[/tex])/-2=-0.80741759643
