30 POINTS HELP PLEASE

Answer 1

Answer:

a=−3, b=−7 and c=3

Explanation:

ax^2+bx+c=0ax

2

+bx+c=0

We have:

-3a^2=7a-3−3a

2

=7a−3 subtract 7a from both sides

-3a^2-7a=7a-7a-3−3a

2

−7a=7a−7a−3

-3a^2-7a=-3−3a

2

−7a=−3 add 3 to both sides

\begin{gathered}-3a^2-7a+3=-3+3\\\\-3a^2-7a+3=0\to a=-3,\ b=-7, c=3\end{gathered}

−3a

2

−7a+3=−3+3

−3a

2

−7a+3=0→a=−3, b=−7,c=3

Answer 2

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

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`
