Question

find the value of M so that the following equation have equal roots 3x^2-6x+m=0​

Answer 1

Answer:

m = 3

Step-by-step explanation:

In a quadratic equation

$a {x}^{2} + bx + c = 0$

roots will be equal when

${b}^{2} - 4ac = 0$

Using the above in given equation, we have

$36 - 4 \times 3 \times m = 0$

$36 = 12m$

$m = 3$
