Question 1116220
{{{ ( x -(-3/2) )*( x - 5/2 ) = 0 }}}
{{{ x^2 + (3/2)*x - (5/2)*x - 15/4 = 0 }}}
Multiply both sides by {{{ 4 }}}
{{{ 4x^2 + 6x - 10x - 15 = 0 }}}
{{{ 4x^2 - 4x - 15 = 0 }}}
-------------------------------
check:
are -3/2, 5/2 solutions?
{{{ 4*(-3/2)*2 - 4*(-3/2) - 15 = 0 }}}
{{{ 4*(9/4) + 6 - 15 = 0 }}}
{{{ 9 + 6 - 15 = 0 }}}
{{{ 0 = 0 }}}
OK
