a=______ b=______ c=_____

c) x²-10x+25=0
a=_______ b=_____ c=_____

d) x²-10x+25=0
a=______ b=_______ c=______

e) -3x²+x=0
a=______ b=______ c=_______

f) x²-16x=0
a=______ b=______ c=______

Answer 1

$a) \ 2x^2-5x+2=0\\\\\begin{cases}a=2 \\ b=-5 \\ c=2\end{cases}\\\\\\b) \ 9x^2-4x+4\\\\\begin{cases}a=9 \\ b=-4 \\ c=4\end{cases}\\\\\\c) \ x^2-10x+25\\\\\begin{cases}a=1 \\ b=-10 \\ c=25\end{cases}\\\\\\d) \ x^2-10x+25=0\\\\\begin{cases}a=1 \\ b=-10 \\ c=25\end{cases}\\\\\\e) \ -3x+x=0\\\\\begin{cases}a=-3 \\ b=1 \\ c=0\end{cases}\\\\\\f) \ x^2-16x=0\\\\\begin{cases}a=1 \\ b=-16 \\ c=0\end{cases}$
