Question

Find the roots of the equation 2x2 + 5x + 4 = 0.

Answer 1

No solutions

Explanation:

2x^2 + 5x + 4 = 0 ---> a = 2, b = 5, c = 4

`x = \frac{-b +- \sqrt{b^(2) -4ac} }{2a}`

`x = \frac{-5 +- \sqrt{5^(2) - 4(2)(4)}} {2(2)}`

`x = (-5 +- √(25 - 32) )/(4)`

`x = (-5+-√(-7))/(4)`

Since the number inside the square root is negative, the answer will be no solutions.

Hope this helps!
