Any equations that is written in the standarm form :
[tex]a x^{2} +bx+c=0[/tex] where [tex]a,b,c[/tex] are real numbers and [tex]a \neq 0.[/tex]
Examples:
[tex]3 x^{2} +5x+30=0[/tex]
[tex]3x(x+5)=10[/tex]
Solution:
[tex]3 x^{2} +15x=10[/tex]
[tex]3 x^{2} +15x-10=0[/tex]
[tex](x+1)^{2}=15[/tex]
Solution:
[tex]x^{2} +2x+1-15=0[/tex]
[tex] x^{2} +2x-14=0[/tex]
