What are the solution(s) to the quadratic equation 50 - x2 = 0?
jekas [21]

Answer:

x = 5\sqrt{2}

Step-by-step explanation:

given, 50 - x^2 = 0

add x^2 to both sides, 50 = x^2

square root both sides, \sqrt{50}\\ = \sqrt{x^{2} }

simplify, 50 / 5 = 10 / 5 = 2

you have a pair of 5's, and a 2, 5\sqrt{2} = x
