Answer:
[tex]a=3,b=7,c=-20[/tex]
Step-by-step explanation:
we are given equation as
[tex]3x^2=20-7x[/tex]
Firstly, we will move all terms on left side
Subtract both sides by 20
[tex]3x^2-20=20-7x-20[/tex]
[tex]3x^2-20=-7x[/tex]
Add both sides by 7x
[tex]3x^2-20+7x=-7x+7x[/tex]
[tex]3x^2-20+7x=0[/tex]
[tex]3x^2+7x-20=0[/tex]
now, we can compare it with quadratic equation
[tex]ax^2+bx+c=0[/tex]
and we get
[tex]a=3,b=7,c=-20[/tex]
