-x² + 7x + 5 = 10 need help ASAP and ols explane if you can

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:

so

lets do addition first:

so

(7+)/-2=-6.19258240357

lets do subtraction next:

(7-)/-2=-0.80741759643
