Answer : 25,-1 are the roots of the given quadratic equation.
Solution : `2m(m-24)=50` <br> `:.2m^(2)-48m-50=0` <br> `:.m^(2)-24m-25=0` <br> ….. (Dividing each term of the equation by 2) <br> `:.m^(2)-25m+25=0` <br> `:.m(m-25)+1(m-25)=0` <br> `:.(m-25(m+1)=0` <br> `:.m-25orm+1=0` <br> `:.m=25orm=-1`
