Question 912130


{{{8x^2 - 4x -24 = 0}}}

{{{4(2x^2 - x -6) = 0}}}

{{{4(2x^2 +3x-4x-6) = 0}}}

{{{4((2x^2 +3x)-(4x+6)) = 0}}}

{{{4(x(2x +3)-2(2x+3)) = 0}}}

{{{4(x-2)(2x+3) = 0}}}

solutions:

if {{{x-2=0}}} => {{{x=2}}}

if {{{2x+3=0}}} => {{{x=-3/2}}}

{{{ graph( 600, 600, -10, 10, -30, 10, 8x^2 - 4x -24) }}}
