If one of the roots of the quadratic equation x^2+mx+24= 0 is x=1.5, then what is the value of m ?

If one of the roots of the quadratic equation x^2+mx+24= 0 is x=1.5, then what is the value of m ? Correct Answer -17.5

যেহতু 1.5 সমীকরণটির একটি মূল সেহেতু ( 1.5)2 + 1.5m + 24 = 0 2.25 + 1.5m + 24 = 0 m = - 26.25/1.5 m = - 17.5
