The equation `2x^(2)+13x+15=0` by
factorisation method

Text Solution

Verified by Experts

By factorisation method :
`2x^(2)+13x+15=0`
`:.2x^(2)+10x+3x+15=0`
`:.2x(x+5)+3(x+5)=0`
`:.(x+5)(2x+3)=0`
`:.x+5=0or2x+3=0`
`:.x=-5or2x=-3`
`:.x=-(3)/(2)`
`(-5,-(3)/(2))` are the roots of the given quadratic equation.
