Sagot :
Use the formula:
[tex]y=a x^{2} +bx+c[/tex]
[tex]a x^{2} [/tex] (quadratic term)
[tex]bx[/tex] (linear term)
[tex]c[/tex] (constant)
Ex.
[tex]3x-2 x^{2} =7[/tex]
[tex]-2 x^{2} +3x=7[/tex] or [tex]-1(-2 x^{2} +3x = 7)[/tex] -> [tex]2 x^{2} -3x=-7[/tex]
Just do the same thing to the other equations. But before you change it to standard form remember to simplify it. Good luck :)

the standard form of quadratic equation is ax^2 + bx + c = 0
where a, b and c are constant values.
example:
[tex] 2x^{2}+5x+3=0 [/tex]
In this one a=2, b=5 and c=3
so in no. 1. [tex]3x-2 x^{2} =7[/tex]
Answer:
[tex]1.2 x^{2} -3x+7=0[/tex]
so your answer should be in this form:
[tex]a x^{2} +bx+c=0[/tex]
where a, b and c are constant values.
