The value of x so that `[[1,x,1]][[1,3,2] , [0,5,1] , [0,3,2]][[1], [1], [x]]=0` is

Text Solution

Verified by Experts

we have `[1" " x" "1][(1,3,2),(0,5,1),(0,3,2)][(,1),(,1),(,x)]=0`
`rArr" "[1" "5x+6" "x+4][(,1),(,1),(,x)]=0`
`rArr" "[1+5x+6+x^(2)+4x]=0`
`or" "x^(2)+9x+7=0`
`therefore" " x= (-9pm sqrt((81-28)))/(2) implies x = (-9 pm sqrt(53))/(2)`
