Solving Quadratic Equations with Square Roots

Solving Quadratic Equations with Square Roots 1.1 - Solution

arrow_back Return to Solving Quadratic Equations with Square Roots

Before we will try to solve the given equation, let's recall the number of real solutions to a quadratic equation depending on the sign of

  • When has two real solutions,
  • When has one real solution,
  • When has no real solution.
Notice that in our case which is positive, so there are two real solutions to the given equation. To find them by taking the square roots, we need to consider the positive and negative solutions.
We found that Thus, there are two solutions for the equation: and
