Question

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

$-x^2-5=16x$

• A. $a=1,b=16,c=5$
• B. $a=-1,b=-16,c=-5$
• C. $a=1,b=16,c=-5$
• D. $a=-1,b=-5,c=-16$

Answer 1

Answer: (A), (B)

The correct options are
A $a=1,b=16,c=5$
B $a=-1,b=-16,c=-5$

Given,
$-x^2-5=16x$

Given equation in standard form can be written as $x^2+16x+5=0$

Comparing the equation $x^2+16x+5=0$ with $a{x}^2+bx+c=0$

then, $a=1,b=16andc=5$ or $a=-1,b=-16andc=-5$
