Answer: 121>0 121=11^2 so Discriminant is a perfect square
=> the equation has 2 roots, which real, distint and rational
Step-by-step explanation:
D=b^2 -4*a*c
b=5 ( coefficient near x)
a=3 (coefficient near x^2)
c=-8 ( coef without x)
D=25+4*3*8=25+96=121
121>0 121=11^2 so Discriminant is a perfect square
=> the equation has 2 roots, which real, distint and rational
