Question

Find the root of quadratic equation 2 x square + x - 4 is equals to zero if there exist by the method of tratak formula

Answer 1

Answer:

x = (-1+√33)÷4 and x = (-1-√33)÷4

formula to find roots

• x = -b+√(b^2 - 4ac)

2a

and

• x = -b-√(b^2- 4ac)

2a

before using formula compare the equation with these format

ax^2 + bx + c = 0

In your case

2x^2 + x - 4 = 0

a = 2

b = 1

c = -4
