How many roots of equation ax^2 b|x| c=0?

Of roots in this case as modulus present; No root is also a case; Check discriminant sign ,draw the graph of equation without taking modulus.don't draw the rough graph on the negative x axis.then reflect the graph on the positive side to the negative x axis; The resulting graph will be of the required equation . read more

1. It may have max 4 roots 2. Mod is present so root of opposite sign is also a root 3. Root with pairs will exist so even no. Of roots only possibe 4. So 3 roots not possible 5. read more

A2A. Given that a and b are roots of the equation x^2 +ax +b=0, we can apply the results for the sum and product of the roots. Sum of roots= a+b = -a, Hence 2a+b=0. read more

It may be possible to express a quadratic equation ax 2 + bx + c = 0 as a product (px + q)(rx + s) = 0. In some cases, it is possible, by simple inspection, to determine values of p, q, r, and s that make the two forms equivalent to one another. read more
