Answer 1

x=−15+√10 or x=−15−√10

Explanation:

Let's solve your equation step-by-step.

(x+15)2−10=0

Step 1: Simplify both sides of the equation.

x2+30x+215=0

For this equation: a=1, b=30, c=215

1x2+30x+215=0

Step 2: Use quadratic formula with a=1, b=30, c=215.

x=−b±√b2−4ac/2a

x=−(30)±√(30)2−4(1)(215)/2(1)

x=−30±√40/2

x=−15+√10 or x=−15−√10
