What are the steps to solving this by completing the square?

a² + 10a + 21 = 0

• Subtract 5 from both sides of the equation

• Subtract 21 from both sides of the equation

• Rewrite the left hand side as a (binomial)²

• Add 25 to both sides of the equation

• Take the square root of both sides of the equation
