Question

If the zeroes of $x^2+ax+b$ have opposite signs but equal magnitude, then

• A. linear term doesn’t exist & b<0
• B. a+b=0
• C. a-b=0
• D. linear term doesn’t exist & b>0

Answer 1

The correct option is A

linear term doesn’t exist & b<0

(x-a)(x+a) = $x^2-a^2$, Hence there’s no linear term
