What are the solutions to the equation x2−12x+100=0?
marysya [2.9K]

Answer:

x=6+8i

x=6-8i

Step-by-step explanation:

x^2-12x+100=0

solve by quadratic formula.

\frac{-b+-\sqrt{b^2-4(a*c)} }{2*a}

\frac{12+\sqrt{(-12)^2-4*(1*100)} }{2*1}

\frac{12-\sqrt{(-12)^2-4*(1*100)} }{2*1}

which is

x=\frac{12+16i}{2}

x=\frac{12-16i}{2}

Simplify.

x=6+8i

x=6-8i

Solved.


Hope this helps.

I'm back I need help with both of these questions
AlexFokin [52]
1st
90+55+x=180 (Angles inside a triangle equal 180 degrees) Solve for x
x = 35 degrees

2nd
2 non-adjacent angle in a triangle is equal to the exterior angles, therefore

25 + x + 15 = 3x + 10    Solve for x
  40 + x = 3x + 10
-10   -1x  -1x  -10

<u>30 = 2x</u>
     2

x = 15 degrees
Therefore angle ABC is x + 15 where x + 15

Therefore angle ABC = 30 degrees

Who ever hand wrote in those degrees/equations didn't really think it out because < A + <B should be greater than 90 not less than 90
