Question

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

$(x+5)(x-11)=0$

• A. $a=1,b=-6,c=-55$
• B. $a=1,b=6,c=-55$
• C. $a=1,b=6,c=55$
  
• D. $a=1,b=-5,c=-55$

Answer 1

The correct option is A $a=1,b=-6,c=-55$

Compare $(x+5)(x-11)=0$

$x^2-6x-55=0$ to $a{x}^2+bx+c=0$

then, $a=1,b=-6,c=-55$
