Question

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

Answer 1

d

Explanation:

Answer 2

D

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
