Question

When b=0 in the equation aײ+b×+c=0,what is the result to a quadratic equation?

Answer 1

Answer:

±$\sqrt{\frac{-c}{a}}$

Step-by-step explanation:

when b = 0 in the quadratic eqn. a²+bx+c=0,

then the discriminant b²-4ac  will become as only -4ac

and so the roots will be

   ±√(-4ac) / (2a)  ( by the formula [-b ± $\sqrt{b^2-4ac}$]/2a )

=> ±√(-c) / (√a)

=> ±$\sqrt{\frac{-c}{a}}$

Answer 2

Answer:

x= root of b square - 4ac

sub b = 0
