Question

30 POINTS HELP PLEASE

Answer 1

Answer:

$\large\boxed{a=-3,\ b=-7\ and\ c=3}$

Step-by-step explanation:

$ax^2+bx+c=0$

We have:

$-3a^2=7a-3$           subtract 7a from both sides

$-3a^2-7a=7a-7a-3$

$-3a^2-7a=-3$           add 3 to both sides

$-3a^2-7a+3=-3+3\\\\-3a^2-7a+3=0\to a=-3,\ b=-7, c=3$
