Question

Please help me!!! Which of the following is a solution of x2 + 5x = -2?

Answer 1

you will need to use the quadratic equation, it can't be factored.

Answer 2

ehuman is asking you to put the given equation into standard form for a quadratic. This is the right move and would enable you to solve the resulting quadratic equation in several different ways, including the quadratic formula. Completing the square is another possibility that involves about the same amount of work as does the quadratic formula.
Good luck.

Answer 3

thank you!!
