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
