Final answer:
To solve the equation 2(x²-5)=93, divide both sides by 2, add 5 to isolate the quadratic term, simplify, take the square root of both sides, and consider positive and negative roots.
Step-by-step explanation:
Steps to Solve the Equation 2(x²-5)=93
- Divide both sides of the equation by 2 to isolate the quadratic expression: (x²-5) = 93 / 2.
- Add 5 to both sides of the equation to further isolate the quadratic term: x² = 93 / 2 + 5.
- Simplify the right side of the equation and solve for x².
- Take the square root of both sides of the equation to solve for x, and remember to consider both the positive and negative square roots.
- Write down the two solutions for x that result from considering both the positive and negative square roots.
Following these steps will yield the solution to the equation. In solving this quadratic equation, students learn the problem-solving strategy and apply mathematical principles to reach the result.
