Question

What are the solutions of 2x2 + 3x= –8?

Answer 1

quadratic equation

Answer 2

2x^2+3x+8 = 0
is a^2 +b +c

find x use

\[(-b \pm \sqrt{b ^{2}-4ac} ) /2a\]

\[x _{1,2} = (-3 \pm \sqrt{9-4*2*8} )/ 2*2\]

\[x _{1} = (-3 + \sqrt{9-4*2*8} )/ 2*2\]
\[= (-3+\sqrt{-57} )/4\]

\[x _{2} = (-3 + \sqrt{9-4*2*8} )/ 2*2\]
\[= (-3- \sqrt{-57} )/4\]

Answer 3

no real solution. if u want the imaginaries ^ should b correct
