Using SET NOTATION, what is the solution set for the following equation? a² - 3 = 22
UNO [17]

The solution set is \{-5,5\}

Explanation:

The given equation is a^{2}-3=22

To determine the solution set of the equation, let us solve the equation.

Adding both sides of the equation by 3, we have,

a^2=25

Taking square root on both sides of the equation, we get,

a=\sqrt{25}, a=-\sqrt{25}

a=5, a=-5

Thus, the solution of the equation is a=5, a=-5

The solution set of the equation is the set which contains all the solutions of the equations.

Thus, writing the solutions of the equation using set notation, we have,

\{-5,5\}

Thus, the solution set is \{-5,5\}
