Question

m^2-1/2m-3=0 solve by formula method​

Answer 1

Answer:

2 , -1.5

Step-by-step explanation:

$m^2-\frac{1}{2}m-3=0$

The formula is : For a quadratic equation $ax^2+bx+c=0$, the roots are given by:

$x_1,x_2=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

So here,

$m=\frac{\frac{1}{2} \pm \sqrt{\frac{1}{4}+12}}{2}$

$=\frac{1 \pm 7}{4}=2,-1.5$
