Question

Compare the given equation with $a{y}^2+by+c=0$ and select correct values of $a,b$ and $c$.

$m(m-7)=0$

• A. $a=1,b=0,c=-7$
• B. $a=1,b=-7,c=0$
• C. $a=1,b=7,c=0$
• D. $a=0,b=1,c=-7$

Answer 1

The correct option is B $a=1,b=-7,c=0$

Compare $m(m-7)=0$

$m^2-7m=0$ to $a{m}^2+bm+c=0$

then, $a=1,b=-7andc=0$
