Question

Use the quadratic formula to solve x2 + 5x = –2.

Answer 1

\(x^2+5x+2=0\)
=> \(a=1, b=5, c=2\)
Then use the quadratic formula

Answer 2

That leaves this for us:

\( \color{Black}{\Rightarrow x^2 + 5x + 2 = 0 }\)

Quadratic formula is:
\( \color{Black}{\Rightarrow x = \Large {-b \pm \sqrt{b^2 - 4ac} \over 2a} }\)
