Solving by factorizaton methodwhat the roots of the givenquadratic equation:-x2+x-20=0are the..​

Answer»

Step-by-step explanation:

4.8/5

61

x² + x - 20 = 0

splitting the middle term ,

x² + 5X - 4x - 20 = 0

x( x + 5 ) - 4( x + 5 ) = 0

( x + 5 )( x - 4 ) = 0

x + 5 = 0 or x - 4 = 0

x = -5 or x = 4

Therefore ,

Roots of given quadratic equation are -5 , 4
