hmm
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.
@hba Why isn't quadrant formula the best method?
