Answer:
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
