Complete the following activity to sovle the quadratic equation by factorisation method : `25m^(2)=9`

Text Solution

Verified by Experts

The correct Answer is:
`-(3)/(5),(3)/(5)` are the roots of the given quadratic equation.
`:.25m^(2)-9=0`
`:.(5m)^(2)-(3)^(2)=0`
`:.(5m+3)(5m-3)=0`
`:.(5m+3=0or5m-3=0`
`:.5m=-3=or5m=3`
`:.m-(3)/(5)orm=(3)/(5)`
