Answer 2

Step-by-step explanation:

Answer

Ad 24 to both sides to clear the constant from the left side of the equation. x2+2x=24.

Remember that (x+1)2=x2+2x+1. so add 1 to both sides in order to complete the square on the left side. x2+2x+1=24+1.

Take the square root of both sides. x+1=±5.

Giving the solutions. x=4 and x=−6
