Often asked: How To Solve Quadratic Equation By Extracting The Square Root?

How do you solve equations with square roots?

If an equation has a square root equal to a negative number, that equation will have no solution. To isolate the radical, subtract 1 from both sides. Solve a radical equation.

  1. Isolate the radical on one side of the equation.
  2. Square both sides of the equation.
  3. Solve the new equation.
  4. Check the answer.

How many solutions are obtained by solving quadratic equations through extracting square roots?

We can extract the roots if we first isolate the leading term,. Apply the square root property. For completeness, check that these two real solutions solve the original quadratic equation. Generally, the check is optional.

  1. Step -by- step explanation:
  2. Step 1: Isolate the x² squared by using inverse operations.
  3. Step 2: Square root both sides to isolate x.
  4. Step 3: Give the positive and negative answer.

What are the steps to solving a quadratic equation?

Step 1: To use the quadratic formula, the equation must be equal to zero, so move the –5 back to the left hand side. Step 2: Identify a, b, and c and plug them into the quadratic formula. In this case a = –3, b = 6, and c = 5. Step 3: Use the order of operations to simplify the quadratic formula.
