and
a:3
b:30
c:-24

Answer 3

3x2 = -30x + 24.
3x^2+30x-24=0

Answer 4

\[3x^2=-30+24\]Divide everything by 3.\[x^2=-10+8\]Put everything on one side.\[x^2+10-8=0\]
Let's use the quadratic formula.\[\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]\[\frac{ -10 \pm \sqrt{10^2-4(1)(-8)} }{ 2(1) }\]\[\frac{ -10 \pm \sqrt{132} }{ 2 }\]\[\frac{ -10 \pm 2\sqrt{33} }{ 2 }\]
\[-5 \pm \sqrt{33}\]
The last answer choice is correct.
