## InsanelyChaotic 2 years ago Please help me????????????? Solve by using the quadratic formula to solve x2 + 6x = -3.

1. satellite73

easier to complete the square $x^2+6x=-3$ $(x+3)^2=-3+9=6$ $x+3=\pm\sqrt{6}$ $x=-3\pm\sqrt{6}$

2. DAVIDFF

x=-0.5505 , x=-5.449

3. edpinho

write it like this $x^{2} + 6x +3=0$ a=1 b=6 c=3, now you cam apply the quadretic formula $\frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }$
