What are the solution(s) to the quadratic equation 50 - x2 = 0?

1.x= +2,5
2.x= 36/3
3.x=+5,
4.no real solution

Need ! give step by step solutions on how to solve number one \frac{9-2\sqrt{3} }{12+\sqrt{3} } number two x+4=\sqrt{13x-20} number three (domain and range) f(x)=2\sqrt[3]{x} +1

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 23 = 10x a. -1.93, 11.93 b. 1.93, -11.93 c. 1.93, 11.93 d. -1.93, -11.93

Find the value of x. give reasons to justify your solutions! c ∈ ae
