Question

Find the condition that
(i) exactly one of the roots of the equation ax^2+bx+c=0 may be zero (ii) both the roots of the equation ax^2+bx+c=0 may be zero

Answer 1

1) we take a=-√4 and x=√2 and b=√2 and c=√4

ax^2+bc+c=0

put the values

(-√4)×(√2)^2+(√2)×(√2)+(√4)=0

-2×2+2+2=0

-4+4=0

0=0

2) a=(-√9) and x=(√2) and b=(√2) and c=(√4)

ax^2+bx+c=0

(-√9)×(√2)^2+(√4)×(√4) +(√4)=0

-3×2+4+2=0

-6+6=0

0=0

I hope it's help you
