Question

Theo started to solve the quadratic equation

Answer 1

Answer:

$x + 2 = \pm2$

Step-by-step explanation:

After Theo added to both sides of:

${(x + 2)}^{2} - 9 = - 5$

He got;

${(x + 2)}^{2} = 4$

Next he took the square root of both sides to get;

$x + 2 = \pm \sqrt{4}$

When Theo simplifies, he will obtain:

$x + 2 = \pm2$

Therefore the second option is correct.
