Question

Using quadratic formula solve the quadratic equation: 2x - 11x + 9 = 0​

Answer 1

Answer:

x=-1 and x=-9/2

Step-by-step explanation:

here a=2,b=-11,c=9

D=b^2-4ac D=121-4×18=121-72=49. therefore,quadratic formula=-b+or- root(49)/2×a therefore x=(-11+7)/4 and x=(-11-7)/4 and finally solving it gives x=-1 and x=-9/2
