Answer:

[tex]\large\boxed{a=-3,\ b=-7\ and\ c=3}[/tex]

Step-by-step explanation:

[tex]ax^2+bx+c=0[/tex]

We have:

[tex]-3a^2=7a-3[/tex]           subtract 7a from both sides

[tex]-3a^2-7a=7a-7a-3[/tex]

[tex]-3a^2-7a=-3[/tex]           add 3 to both sides

[tex]-3a^2-7a+3=-3+3\\\\-3a^2-7a+3=0\to a=-3,\ b=-7, c=3[/tex]

Answer:

Answer:

a=−3, b=−7 and c=3

Step-by-step 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
