Answer 1

Answer:

m=6

Explanation:

Given quadratic equation,

3x² + mx + 3 = 0

It is in the form of ax²+bx+c=0

So first write the mutliples of ' a×c ' from the given equation,

a×c = 9x²   ⇒ multiples of 9x² are 3x and 3x     ( given in question as equal roots)

so the equation can be written as,

3x² + 3x + 3x + 3 = 0

3x² + 6x + 3 = 0

Hence,

m=6
