Question

find the roots of Quadratic equation and 2x^+X+4 by
applying the quadratic formula​

Answer 1

Answer:

Step-by-step explanation:

2x^2+x+4=0

Here, a=2, b=1 and c=4

Discriminant=√b^2-4ac

=>D=√1^2-4×2×4

=>D=√1-32

=>D=√-31<0

It has no any roots because it's discriminant is smaller than 0....

Answer 2

Answer:

Quadratic formula = - b +or- square root of b^2-4ac the whole divided by 2a
