Here's ur solution buddy,
2x²-7x=39
_____________________________
Expressing as ax² + bx +c=0
_____________________________
=> 2x²-7x-39=0
=>2x²-13x+6x-39=0
=>x(2x-13)+3(2x-13)=0
=>(2x-13)(x+3)=0
2x-13=0,
or x+3=0.
___________________________
Zero product rule
___________________________
=> x= 13/2, or x= -3.
Thanks.
