Part 1: Use the quadratic formula to solve x^2 + 5x = –2. Part 2: Using complete sentences, explain the process you used. Part 3: Why is the quadratic formula the best method to use?

Well First of all compare your equation(x^2+5x+2=0) with$\huge\ ax^2+bx+c=0$ And find a,b and c.

Then Use the quad formula to determine x, Which is $\huge\ x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }$

Btw,The Quad Formula is not the best method.
