What would be the most logical first step for solving this quadratic equation? x2 + 2x + 13 = -8 a. take the square root of both sides b. divide both sides by x c. subtract 13 from both sides d. add 8 to both sides

D

Step-by-step explanation:

Given

x² + 2x + 13 = - 8

To be able to factor the quadratic and go on to solve we require the equation to be in standard form, that is

ax² + bx + c = 0, thus

Add 8 to both sides ← first step, gives

x² + 2x + 21 = 0 ← in standard form

the answer is  

a.
