Question

What are the solutions of 3x2 + 4x = -5?

Answer 1

is that 3x^2 (squared)?

Answer 2

\[3x^2+4x=-5\]
Add 5 to both sides. Now your equation looks like this
\[3x^2+4x+5=0\]
Now you can use the quadratic formula from here. Do you know the quad. formula?

Answer 3

x = [ -b ± sqrt(b^2 - 4ac) ] / 2a

Answer 4

there you have your tools

Answer 5

\[x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

This is just in case you needed it. Just plug in the 3 4 and 5 for the correct variable then solve. Do you have any questions?
