Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
2\5 + 2\4
Lcm of 4 and 5 is 20
So 20 divided by 5 is 4 × 2 = 8 and 20 divided by 4 is 5 × 2 = 10
10+ 8 =18\20 = 9\10
