two x squared minus negative 11x greater then 40
2x^2+11x-40=0 using quadratic formula
x is minus or plus the root of b squared minus 4ac divided by 2a
x=10/4 or x =-32/4
x=2.5 0r -8
The above of values of x satisfies the inquality
The value of x I have obtained using quadratic equation and both answers satisfies the inequality if you take the value of x to be 2.5 or -8 you will get the same answer
