Problem:
2x(x-7)=6 standard form
Answer:
[tex] \huge \underline{\boxed{\sf \red{2x^{2}-14x-6=0}}}[/tex]
Expand the product and make one side of the equation zero. If you move a variable or number into another side that have a positive sign you'll change it to negative. If the sign is negative change it to positive.
- [tex]\large\rm\pmb{2x(x-7)=6 }[/tex]
- [tex]\large\rm\pmb{2x^{1+1}-14x=6 }[/tex]
- [tex]\large\rm\pmb{2x^{2}-14x=6 }[/tex]
- [tex]\large\rm\pmb{2x^{2}-14x-6=0 }[/tex]
- [tex]\large\rm\pmb{a=2,b=-14x,c=-5 }[/tex]
Don't forget the sign.
